As you said "I'd like to experiment"

We don't put everyones random experiments in the kernel or we'd have a
kernel that had a million unfinished project hacks.

Suppose this doesn't work out - how do we get rid of the new hack,
someone might by then have decided to depend upon it. More crud, more
APIs we can't get rid of

More importantly there is an API *in* soundcore for registering sound
devices in the OSS category. You can use that.

Not only was that interface written precisely to allow the kind of
sharing in question but it will also let you mix OSS, ALSA *and* your own
experimental device work at the same time because it hands out minor
numbers properly.

Given we have an existing proper interface for this I think this hack
belongs in a private dev tree only. In fact I suspect it belongs in the
bitbucket and experimental code should be using the proper provided and
exported interfaces as it will need to if it is ever going to be accepted
upstream.
