I wasn't (primarily) talking about fixing this particular issue.
Time needs to be made available also for the upcoming 2.4.6 and 2.5.3
releases (which should, IMO, get priority over a 3.0 bugfix release
at this point)

I think 3.0.1 should also address other serious bugs in 3.0, such
- various IDLE bugs with non-ASCII characters (2827, 4008, 4323, 4410)
- various ways to crash Python through the buffer protocol
  (4583, 4509; also 4580)

IIUC, you want the bugfix version number to be sync'ed. I don't
think that is a useful thing to have.

I don't recall such policy, and I can't see anything wrong with
including performance fixes in a bug fix release. Maybe you were
confusing this with whether performance fixes can be considered
release-critical (which they shouldn't, IMO)?
