CUSE is generally not a bad idea, though it has problems, most
prominently in the fact that the OSS timing model is simply too broken
to make CUSE work correctly with /dev/dsp mapped to PA. Also, not sure
how emulating /dev/dsp is supposed to work in a multi-user env.

I think that the need for emulating OSS is simply not as big as people
think. At least if I interpret the number of bugs that got posted
against F11 correctly, the need for OSS really is not that big

Judging from our experiment in F11 I really see no need for enabling
the cuse emulation stuff in Fedora.
