Maybe twine and bumpversion could be added to develop reqs. But this is a matter of choice ;). Well done, sir!

@martinbabka Good point, I'll leave it as it is for now. I do think that we'll have to re-visit and cleanup setup.py though. On the other hand, neither of them is required to run make release-check to move it to test requirements...but maybe extras_require, we'll see ;)
