@tie What's the status of this PR? Are you still working on it?

@mojatter Can you please sign the CLA (see https://github.com/lucas-clemente/quic-go/pull/3465#issuecomment-1170788494). We'd need that so we can merge the PR.

Thank you!

Why can't we make this analogous to the H2 client?

Yes, something along those lines. A few thoughts: 1. It probably makes sense to only do this for Initial packets. 2. It should use the CONNECTION_REFUSED error. The tricky thing...
