(a) we don't have a stable series any more
and
(b) this isn't an abi change, it's a system management change.

If you don't think we can make those, then I assume that you also claim 
that we can't do thigns like commit 1b5e62b42, which doubled the writeback 
dirty thresholds, or any of the things that changed how dirty accounting 
was done in the first place?

I would _love_ for distros to do the sane thing, but they don't. That's a 
fact.
