Our strategy has been to port releases, rather than work in progress, as an effort to conserver our resources.
Since 4.0 is going to be a total reorganization of the ACS, with 3.3 being a large step from 3.2, at the moment our goal is to firm up a 3.2 final release. We may skip 3.3 altogether and just work on 4.0.
Of course, if you're interested in porting Karl's stuff now, no one's going to tell you not to! This is just our thinking at the moment. 4.0's going to be a lot of grungy, grungy work...
