Indeed, like I said I think most of what I suggested only makes sense
with a transparent remapping of control names for application usability
reasons if nothing else.  PCM specification is the only thing I can see
being useful right now but that's definitely something that could just
be bolted on the side of the existing stuff, it shouldn't impact it
directly.

What would be nice now would be to tweak the configuration file format
to support at least the control remapping, though (so it'd only support
a fixed list of target controls but it'd use the standard names, for
example).  That would mean that when someone does implement more
advanced functionality there's more chance that the configuration file
format would be static.  Configuration file format changes are a pain to
manage over upgrades, especially for distros, so if they can be headed
off in advance that'd be a win.
