I wouldn't revert; Python 2 should not hold anyone from keeping packages
up to date.

My opinion is that moving packages about to be removed is not worth the
hassle.  Most Python 2 packages are already in a single module: the
gigantic python-xyz.scm ;-)

I just committed a series of python2-* package removal, along with using
this port for our syncthing-gtk package.  It now builds, at least!  See
commit de8dc9039b.

Fair enough.  Removed in 23a5dcce1d.
