Like I said, it was very preliminary research... I reached the bit where pypi2nix did "nix-env -if https://github.com/garbas/pypi2nix/tarball/master" and wasn't super happy about the implications of "just use master" for production readiness.
If it works, though, that's great!
The more general point though is that in my experience no tool is perfect, or completely done, or without problems. E.g. the cited https://grahamc.com/blog/nix-and-layered-docker-images suggests you need to spend some time manually thinking about how to create layers for caching? Again, very preliminary research—I know people are using it, I'm just skeptical it's a magic bullet because nothing tends to be a magic bullet.
