I think there's a general consensus these days that EXPERIMENTAL is
pretty meaningless so we probably shouldn't bother with it.  The text is
also a bit confusing, it enables use of the media controller API for
ALSA devices really.

I have to say I'm also a bit surprised that there's no core framework
for media controller and we're open coding ioctl() implementations here,
I'd have thought there would at least be a way of enumerating all media
controller devices in the system...
