Before we proceed any further, do you have a sponsor for this PEP? It's an important first step.
Please re-read PEP 1, specifically:
https://peps.python.org/pep-0001/#submitting-a-pep
I've renamed the PR to make it clear that 738 has not been assigned yet, we need a sponsor first.
Edit: 738 (and 739) has already been assigned but not yet merged.
There's also no Discussions-To: header. Where was this proposal discussed prior to writing the PEP?
The proposal wasn't discussed and I do not have a sponsor, yet, at least not for the text as it is. I thought Christmas is coming, maybe I can make a wish. :-) I wrote a PEP, because there was already PEP 476 to change the certificate verification for HTTP libs and it was a recommendation to write a PEP over in a Cpython discussion. As far as I understand, writing a PEP seems to be a very specific thing, while for me it feels like the most complicated way of filing a security ticket I have ever experienced. Nevertheless, I can start a discussion at discuss.python.org, maybe in the Ideas section.
While you can propose a PEP, there is still a certain procedure to be followed and some pre-requisites. I know not everyone is keeping up with core devs workflow and process, so you might find my PEP Talk useful. In this talk, you'll learn about what PEPs are, what might need a PEP, and how Python community can participate in the PEP process.

Yeah, to file a security ticket you typically email [email protected], but given that there’s already public discussion of the problem, you would generally just be advised to open a regular ticket. The need to write a PEP would come up in the discussion on that issue — or not. I don’t immediately see why this particular issue requires a PEP. So either discuss.python.org or GitHub.
Whoa. I got the chronology all wrong. In the CPython issue you referenced (which you should have mentioned in the PEP and in the initial comment) it's clear that @vstinner wants to sponsor your PEP, but he prefers it if you contact him, asking him to be a sponsor, so he can guide you through the PEP authoring and submission process. You already submitted an earlier draft PEP, which was closed for this same reason. I am honestly not sure why you didn't just contact him (possibly via the CPython issue) instead of once again breaking protocol and submitting a PEP without context.
I'll leave it to @vstinner to deal with the rest of the process now, I am done trying to mentor you, sorry.

Ah right. So this PR is a duplicate of your https://github.com/python/peps/pull/3537 from last month.
What happened:
-
In April 2022 in https://github.com/python/cpython/issues/91826#issuecomment-1108375164, @vstinner suggested a PEP is needed as the change would impact many users.
-
After more discussion, last month Victor offered to sponsor such a PEP.
-
@nitram2342 wrote a PEP and opened PR https://github.com/python/peps/pull/3537, but hadn't talked to Victor so it came as a surprise, who said he would have preferred to been asked first and given the chance to review before it was posted. This is after all the PEP process.
-
In https://github.com/python/peps/pull/3537#pullrequestreview-1737941767, I suggested Martin contacts Victor privately so they can decide how to proceed, and we close it until they agree on the text.
It seems that hasn't happened, and we're back to needing a sponsor, if we want to take the PEP path. I think a discussion at discuss.python.org is the way forward, and hopefully you can find a sponsor there.
Let's close this PR as a duplicate, and if you find a sponsor, then you can open a new PR once they're on board.
Let's open this for a bit longer.
@nitram2342 Please will you contact @vstinner and see if he's happy to sponsor? You can find his email on his profile.
Let us know if you've any questions.
Thanks!
Yes, this pull request is the second attempt for a PEP. What I did not understand at the time of the first attempt is that there is a sponsor for a specific form of a PEP and not the general idea. I did it wrong and added @vstinner as sponsor without asking him and going into discussion. So, after the first pull request, I contacted @vstinner, because he offered to be a sponsor, but he had no time to review the PEP draft. If people don't have time, that's the way it is. I didn't want to interrupt any further.
I started this pull request without a sponsor. I assumed there would be a sponsor if someone considers this important enough.
Meanwhile I opened a discussion over on discuss.python.org. We will see where the discussion leads.
Thank you! For reference, here's a link to the discussion: https://discuss.python.org/t/42313
