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. > Moreover, simply invoking "pytest-3" is not enough, one should be using: > > for pyvers in $$(py3versions -vr 2>/dev/null) ; do \ > python$$pyvers -m pytest ; \ > done > > otherwise, only the default version of Python3 is tested, and we really > want to test with all available versions (so we get results whenever > we're transitioning to a new Python 3 version). 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.
