I HATE PYTHON

Yes, insufficient caffeine on a lazy Saturday morning caused me to confuse netaddr for the real culprit, netifaces. If it's working now that may well be due to changes since I ran into this issue - uv development is almost as fast as its runtime, it can be hard to keep up. It may also have been using a more modern Python version than netifaces wanted? I honestly can't recall the details, and I'd have to do a lot of work to rebuild enough context to try and replicate the issues.

One of the things that would have been useful, I think, would be a way to use the system python's packages to resolve certain dependencies - possibly by importing them into the managed python install, or into the venvs that uv builds. Obviously assuming you're working with sufficiently compatible versions (which may well be hard to figure out) . . . It's not going to be something you want to use regularly, and it'd need to be explicitly chosen per-package, but it might be useful if the problem packages are a ways down the dependency tree and unresolvable otherwise.
