I think we're talking at cross purposes. The point I'm making is that
there are lots of issues where popularity as a third party module
isn't really a viable test for whether a feature is sufficiently
awesome to be in core python. As part of determining whether I thought
it was appropriate in this case I essentially just asked myself
whether any of the really good and necessary parts of Python would
fail to be readmitted under similar circumstances, and I think the
answer is that very few would come back in. To me, that indicates that
this isn't the right way to address this issue, although I admit that
I lack any solid proof to base that conclusion on.
