Known breakages are easier to deal with than unknown ones :)
I think that that "bug compatability" is basically a policy on *which*
regressions you'll see vs *if* you'll see a regression.
We'll never pull in a commit that introduces a bug but doesn't fix
another one, right? So if you have to deal with a regression anyway,
might as well deal with a regression that is also seen on mainline, so
that when you upgrade your stable kernel you'll keep the same set of
regressions to deal with.
