I don't see why not. If we don't, I'll probably be one of the loudest ones asking for it (I too use our servers to do my own 'stuff').
The operative phrase, though, is "out of the testing stages". We really do like to see something like MySQL be not only out of beta, but running well on a variety of systems for some time before we support it.
That said, 4 has been in development and Q/A for quite some time, so we'll probably jump onto it as soon as we can give it a decent round of testing. I'm not in the Admin team, though, so it really is their call.
I'd be very interested in seeing how well MySQL atomic operations work for you, though, if you decide to go that route. Most of the stuff I'm working on now doesn't really need full transaction support, and if I can find a speedier way to ensure data integrity without them I'd be pretty happy.
