Ok. And am I correct in assuming that if the ABI change would break an
OOT module, you would normally change the ABI number?

Which OOT modules are important enough to result in ABI number

How are the symbols that those OOT modules use communicated to the
kernel team?

What does the kernel maintainer team feel should be done by the
maintainer in this case to ensure continuity of upgrades and rebuilds
of the OOT modules?

I personally don't think a Provides: solution is going to be feasible
for technical reasons, and coordination reasons. Lets restrict
ourselves to discussing the technical reasons why a solution is
infeasible, rather than possible monetary impetus required to
implement them.
