Yes, this is the obvious downside.  Ideally we would never do this, but in this

It shouldn't be hard to make a pythonFull "pseudo-package" that has python and
all modules as propagated build inputs / user environment packages.  Then
they'll show up in the user environment if you do "nix-env -iA pythonFull".
