Looks good to me (and works on my setup)!

Did you have anything more you wanted to add or edit ?

Also, I don't really know how to proceed with this "nested PR", since I have an outstanding PR in the upstream NixOS#53033.
My plan at the moment is to merge this request in my branch and update the upstream PR (and hope for a merge 👍 ).

Wait for a little bit I'm still working on fixing openssl 1.1 support in the LTS branch. I was planning on doing python3 in lts branch but it seems to be a bit more involved than the openssl fixes I almost have completed.

Good to go.
