Mea maxima culpa. I'll add a new section to the start of PEP101 and PEP102 about communicating with the appropriate people directly.
We had a bunch of testers try out the release candidates on various Mac OS X releases - they reported no breakages. There's also been few/no checkins to the Mac-specific chunks of the tree for the release23-maint branch.
I'm happy to store up checkins for the 23 branch for a couple of weeks to give you time to do a release if you so wish (consider it penance for my forgetting to email you).
