It's offtop here but that bug is actually not fixed. It is perfectly possible to set antialias to "false" in ~/.fonts.conf (resulting in Qt3 and GTK apps to stop using font smoothing) and still have got it enabled in wine-1.2-rc4 due to Xft.antialias set to "true". Easily reproducible on my workstation, I may provide the configuration details and proving screenshots if needed.
The Wine strategy is an approximation, in particular because we also have to respect what the app itself requests. It's quite possible that behavior with contradictory configurations doesn't quite match what other apps do; I don't think that's a particularly interesting case. Besides, as you mentioned, there's no clear standard to follow anyway.
