One such reason is that users will then hit the regression when they upgrade to the next -stable version anyways. >Every fix I make I consider labeling it for stable.

People are already "lazy". You are actually an exception for marking your commits. Yes, folks will chime in with "sure, I mark my patches too!", but if you look at the entire committer pool in the kernel you'll see that most don't bother with this to begin with.=
