I don't think we can drop multilib until at least steam/wine are
ready
for it at least.
Will they ever be though? Thanks to Wine I can run an open source
game that cannot move to 64bit support because it's dragging binaries
for which it doesn't have source code. I reverse-engineered one of the
DLLs myself and helped them get closer to their goal, and it took
months, but I still don't know when the authors will finally manage
the transition without sacrificing features.
I can't imagine how someone would deal with 32bit Wine support going
away for a completely closed source game or application for which they
may have purchased a license years ago that will only run on Wine or
Windows. I'm certainly not opting for the latter...
