The python2 interpreter will be supported, but nothing else will, so I
don't see the point of this compatibility.  I don't think that "keep you
old packages from the previous release" is a great upgrade path.

Anyway, my point is that we should collective aim to be consistent
across the Python packages. The fact that some packages have made their
"not *3" binaries be the python3 versions, and others not, due to
arbitrary individual maintainer decisions, is a mess.

Sure, but that only applies for package maintainance. People who just
want to use pytest to test their Python code have a (IMO pointless)
divergence from upstream. This made some sense when there were 2
supported Python ecosystems, but that's now in the past. We could take
the opportunity to fix this.
