The RMT has the final word on anything related to the release, but we
are discussing about adding something new to a branch that has gone
through two beta cycles with a GA targetted around the end of
September ~ beginning of October based on the trends of the recent
years. That's out of the picture, IMO. This comes once every year.

I agree about the low-risk argument, though. This is just new code.
