We can always delay removal if a particular release comes sooner than
originally expected. The deprecation policy is just that we specify
minimum version numbers at which the features can be removed. It's not
really a firm schedule.

I do take your suggestion to heart, though. We shouldn't remove stuff
faster than 12 months or so. I just think that it should modify our
release process, not our "marking for deprecation" process.
