On the same note, wheel currently writes "2.0" as its metadata version.
Shouldn't this be changed into 1.3 (along with ditching metadata.json)?


Should wheel change to emit 1.3, or should the PEP change to become 2.0? I
know there were great hopes for "metadata 2.0", but given that there are
bazillions of packages out there with a metadata version of 2.0, we're
never going to be able to meaningfully use that version number for anything
else, and it's confusing if when reading package metadata the ordering is
1.2 < 2.0 == 1.3 < 1.4. So maybe we should declare that this update is 2.0
or 2.1, the next one will be 2.1 or 2.2, etc., and if anyone asks why the
major version bump, well, it's hardly the strangest thing we've done for
compatibility :-). (And in the unlikely event that PEP 426 lurches back to
life, we can make it 3.0.)
