It should be several release cycles before hand to give plenty of time for feedback and consensus. I think it is generally accepted that if a kernel feature has no known users and no dedicated maintainer then that code should be removed. The powerpc celleb platform was in a similar situation. Not so many available, no real dedicated mainliner, etc. Support was removed [1], and I don't know of any problems that came of it.
