One thing I was thinking to do after the 1.4 split was to duplicate
the plugins/python directory into
{ plugins/python2 , plugins/python } (where the latter would be
Python 3 / current Python only).

It would let us remove awkward conditional code and make it much
easier to parallel build python2 & python3 plugins.
