I can't speak for AJ, who is the only person who can commit to the wine
upstream git tree, but I'd say there is a good chance of that.

I counter with the same logic:
What's the point of having WINE->PULSE->ALSA instead of WINE->ALSA? Remove
pulse from the equation (and use dmix where required) and you have a better
working solution.

Of course, pulse is cross-platform, so works on Solaris, *BSD, etc., where ALSA
is not available, but OSS is. So you could then have WINE->OSS4 instead of
WINE->PULSE->OSS.

No, pulse is not a de-facto standard. It's not installed by default by the
majority of distros. ALSA is the de-facto standard for sound in Linux; OSS is
still available in the kernel tree, as well as by ALSA emulation, although the
best OSS-based solution would be to compile OSS4 which is not in the kernel due
to license disparity.

No, that's not a good reason. Your performance has most likely improved due to
improvements in winealsa to make it work better with pulse. For more reliable
results, pulseaudio can be removed completely and safely, even on Ubuntu.
