Good point. I reached out to the bug owner. He got it 'mostly
working' but got hung up on porting the proton unit tests. I've
offered to help this along and he's good with that. I'll make this a
priority to move this along.
In terms of availability - proton tends to do releases about every 4-6
months. They just released 0.9, so the earliest availability would be
in that 4-6 month window (assuming that should be enough time to
complete the work). Then there's the time it will take for the
various distros to pick it up...
so, definitely not 'real soon now'. :(
