there will never be a Python 2.8. There's certainly no desire to add new
syntax so there would be code that will run in Python 2.7.11 only, and not
in earlier 2.7 releases.

Exactly - it's only in truly exceptional cases like the PEP 466 & 476
network security changes that we'll add features to Python 2.7.

Keyword-only arguments are certainly a nice enhancement, but their absence
isn't actively harmful the way the aging network security capabilities were.
