> remove those versions, not put them in containers

I don't know how to fix this, but perhaps i can ai it and release something on my github if i manage to cobble something together.

These aren't "services" that anyone has access to, except myself; "clients", UIs, and things like whisper.

IF someone were to pay me, I'd figure it out. I'm friends with maintainers and that isn't my style. archiving is.

to wit, i expend no more energy than necessary maintaining other people's code.

I really do not follow what you are trying to convey here.

If there are vulns, and you are using software from nixpkgs, there are tools to get yourself notified about vulnerable packages.

If you want to run vulnerable software on-demand, you can just boot the machine/vm up when needed? If you want to patch stuff yourself, nix makes it trivial to apply your own patches to already packaged software.
