It's my opinion that the lack of a stable kernel device driver ABI is a large part of Linux's success, and whatever the reason, under its current management that's not going to change (that management being of course another reason it's so successful). Although depending on how bad systemd is in the wild, a sufficient critical mass for a stable device driver ABI just might be come to be.
