Moving feedback back to the backport considerations thread...

Of course!  The underlying guideline is that all modules built for
2.4.16, blissfully unaware of the 'future' Protocols schema, still "just
work" without recompilation or reconfiguration.  If this proves impossible,
the backport solution is probably to keep H2Protocols in place on any
legacy module, and reserve the generic Protocols for trunk and future

ASF mod_ftp is an example of an alternate protocol provider that (as of
trunk flavor) should still just work.  It happens to be the most convenient
for me to compare, but is by no means the only example.  I have a couple
patches to integrate before proposing a mod_ftp 1.0.1 tag for a release
vote, but expect to immediately afterwards start to integrate the proposed
Protocols behavior in httpd trunk, and be ahead of the game this round
rather than behind in the case of 2.4.x :)
