That certainly softens the blow but might still cause unnecessary
suffering when maintaining/resurrecting legacy Python code.

How about blocking the introduction of new keywords for ever except if
you specify:

   from __py35__ import syntax

Eventually, every Python module would likely begin with a statement like
that, and it would document the assumption more clearly than __future__.
