No. Very few linux application use /dev/audio anyway and ...

Yes, sort of by definition. My understanding of /dev/audio is that its
just /dev/dsp with a different set of defaults (i.e. 8 bit, ulaw, 8kHz).
You can open /dev/audio and reset the h/w parameters if you want,
which then makes it existence as a separate inode fairly pointless.
>(c) I'm obliged to emulate 8 bit, ulaw, 8K whether I like it or not?
Absolutely not. The OSS programmers reference makes it abundantly
clear that the application is at fault if it expects to be able to ask
for these settings and get them unconditionally. It goes further, and
makes it clear (to me, at least) that you may *never* be able to get
the settings requested, even if they make perfect sense.
