Umm.. Complain more. I upgrade kernels a lot more often than I upgrade
distros, and things don't break. They're not allowed to break, because I
refuse to upgrade my user programs just because I do kernel development.
But I'd only notice a small part of user space, so if people don't
complain, they break not because we don't care, but because we didn't even
know.
So if you have a user program that breaks, _complain_. It's really not
supposed to happen outside of perhaps kernel module loaders etc things
that get really really chummy with kernel internals (and even that was
fixed: the modern way of loading modules isn't that chummy any more, so
hopefully we'll not need to break even module loaders again).
If we change some /proc file thing, breakage is often totally
unintentional, and complaining is the right thing - people might not even
have realized it broke.
At least _I_ take breakage reports seriously. If there are maintainers
that don't, complain to them. I'll back you up. Breaking user space simply
isn't acceptable without years of preparation and warning.
