Right, the baseline there is really 2.7.5 + selected backports, and
the backport set is small for RHEL 7.x, and even smaller for Debian
stable and Ubuntu LTS. Even getting the network security enhancements
backported has proven to be challenging - other feature updates have
next to no chance.

Given that, I don't see a compelling reason to change the existing
policy - the "no new features in point releases" restriction only gets
waived in cases that have implications beyond the Python 2.7 process
itself (which pretty much restricts potential waivers to network
security enhancements).

Cheers,
Nick.
