I don't want to block this if there's actually a reasonable amount
of demand.  Let's wait a bit to see if other requestors show up.

If we do go forward, I think the flake.nix file needs a header comment
covering at least these points:

1. An explanation of what it is/does, aimed at people who never heard
of Nix.  Doesn't need to be long.  (Some of our other root files
could use some self-justification too :-()

2. A suggestion to add thus-and-such personal ~/.gitexclude patterns
if you want to use Nix.
