Some, but not all, and you know damn well where the rest is coming
from (kABI is a four-letter word and anything that smells like
a slippery slope towards that in mainline kernel is not a good
idea, to put it very mildly).

It's really very simple:
	(1) There are too many exports
	(2) "should not break any code that uses only exported symbols" is
a very strong constraint.  Too strong to be feasible.
	(3) That constraint has become too strong because module authors
kept adding exports.
	(4) Unless the number of exports is trimmed by at least 1--1.5
orders of magnitude, forget about any such promises.
	(5) Trimming it down is unacceptable for module authors - the same
people who'd created that coprostalagmite in the first place and who keep
asking for such promises.

What can one do?  Well, get the code merged or maintain it on your own.
If the subset of exports you are using is relatively sane, the latter
option will cause you relatively little PITA.  If it's not, well, at least it
doesn't become a pain in our arses...
