That makes a lot of sense to me, although I'm not a pytest developer
and have no idea what the pytest rules for making backward incompatible
changes are.

After reading this thread, I chimed in on GitHub -- aliases are almost
never a good idea, but the fact that there's an alt_spellings list in
the code means that it really should just be renamed. This should be as
simple as a deprecation warning, time period, and users doing a
s/parametrize/params/.
