It's a useful feature.  We migrated from 2.6 to 2.7 in one project,
which meant everyone had to re-run bootstrap.py with the right Python.
*Of course* some people/CI bots did not do it, which ended up wasting
time chasing strange errors.

I wish I'd noticed buildout-versions had this check before I hacked up an
ad-hoc Makefile snippet of my own.
