I think we've reached a consensus on those two PEPs.
Although, there's one last point that was forgotten in the discussions : I've introduced "rc" in the pre-releases markers, so PEP 386 is compatible with Python's own version scheme. "rc" comes right after "c" in the sorting. It's slightly redundant with the "c" marker but I don't think this really matters as long as consumers know how to order them (a < b < c < rc). I have also stated that "c" is the preferred marker for third party projects, from PEP 386 point of view.
Is there anything else I can do to make those two PEPs accepted ?
