Userland guarantees are easier to achieve than private kernel interfaces.
Compilers have been binary compatible always, though newer versions were
pickier at times which caused some minor grief (though that had nothing to
do with the video driver stuff).
By and large, things are broadly compatible. in the minor releases. And
that's a good thing since we need packages for fewer release trains. But it
also means things can take longer to get into a release. It's a balancing
act, really, that we set the balance for decades ago and we may benefit
from a close re-examination to see if a different model would let us use
resources better and/or deliver features more quickly.
