 nixpkgs typically only has a single version of Python packages.

 Newer versions won't support Python 2, for example the `txaio` in today's
 version doesn't support Python 2 (as packaged, anyway).

 Older snapshots aren't always going to include what we want, e.g. future
 0.18.2 isn't available in 19.09 snapshot.

 So in order to use nix, tahoe-lafs would have to maintain its own package
 snapshot. This seems like more work than it's worth, so I suggest
 disabling nix until the Python 3 port is done. At that point nixpkgs'
 "only include the latest package" approach becomes feasible again.
