considering that alsa API and drivers is pretty stable i see no problem in OSS removal. When writing a program adding oss compatibility seems faster, but, creates lots of problems. check the skype example (yes i know it's closed-source). 99% of sound problems users have is due to OSS driver usage.
that's a big problem. Needs a radical solution. Considering aoss works in 50% of cases i suggest aoss improvement and not OSS keeping in kernel.
A good idea could be an OSS API layer over Alsa-lib...but i personally don't know how much can that costs, considering you should link against alsa-lib too.
This discussion seems a no-sense. Kernel API continues to change every -rc and noone cares that. OSS has been deprecated for a lot, and it's as old as moon.
