I know that not too many people are using wine like that, but right now it works fine and I'd kindly ask for it to keep working, rather than get broken.
Nobody is suggesting to change the behavior for apps that don't use wineconsole. The only suggested change is to default to X instead of curses for the console window. If you don't see curses crap now, you won't see X crap with the change.
Cool :) Keeping things excrement-free is the way (aren't I in a funny mood today) :)
