Anyway, we are trying not to do this, but it does, and will, occasionally happen. Look, we just did that for one platform for 4.9.94! And the key to all of this is good testing, which we are now doing, and hopefully you are also doing as well.
Yeah, but having to test stuff with known breakages is no fun, so we try to avoid that
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.
