--- Comment #26 from Peter Seebach winehq@seebs.net 2010-01-03 21:04:38 --- Yes, in theory, it is up to them to pull it in. But they're not going to for a LONG time -- in practice, there's no chance that this will be fixed before Ubuntu 10.04, in April, for instance.
Putting in the workaround for now, or making it at least available as an option, would allow users on actual distributions which exist to use WINE without horrible key repeat problems.
