I think this whole discussion misses the essence of the new development
model, which is that we no longer do these kinds of feature-based major
milestones.  If we want to to deprecate lots of drivers (which I
personally would advocate against -- I have built systems specifically
to run a real floppy drive since the Linux floppy driver is amazingly
flexible and can read/write a lot of formats that nothing else can,
including USB floppies) then we should do that in the normal course of
action, incrementally, and listed in feature-removal-schedule.txt, not
all at once due to some arbitrary milestone.

We have found it works better this way.
