What makes you think that module interfaces _exist_? Over the years
we'd got a pile of exports. Maybe 5-10% of it could form several
more or less sane interfaces. And that's being very optimistic.
But try to get those interfaces and guess who'll scream bloody
murder? That's right, the 3rd-party module developers. The same
people who presumably want stability. Because all that dreck had
been exported on someone's requests.

Eh? Funny, but in the next xterm I've got an ssh session to RHEL-5
box. 2.6.18+many backported patches... FC is simply following
mainline, but that's a separate story...

"Drop-in" in which sense? That out-of-tree modules keep working?
Not really...
