Suggestion: defer front-end-checklist to third-party.
There is a great front-end launch checklist here: https://github.com/binhnguyennus/front-end-checklist
It even has an associated web-app: https://frontendchecklist.io/
I propose that we keep the checklist file, but that we remove the bulk of the content - keeping just SL-specific stuff if there is any, and we link to the third-party list at the top of the file.
I agree on deferring a lot of these decisions to 3rd-parties.
We have private repos so I guess we'd need private checklists too, and group support. Does that webapp support that? I'd feel safer about a markdown file in a repo because it can still be there in a year from now, whereas an app might disappear, but I'm open minded about looking for alternatives.
