Yep, but the question i was getting at was whether this would be developed purely for 2.2.1 (and get left behind as the interface designed for 2.0.5 did because it was designed for 2.0.5 when 2.2.0 was trunk), or if it would be built for 2.4.X or possibly both (at least tested in both during development ...?).
I mean, if this is "developed" in the "branch" instead of the "Developer Trunk" ... it will not be shocking when it gets left behind.
Not to say anything about it no being useful, but the limitations on usefulness for software can impede progress dramatically. (I have a client on 2.0.4 who won't leave it because adaptations built in 2.0.4 would have to be "brought up to date" and he doesn't want to pay for it ... he says he'll wait until everything he added to 2.0.4 is IN trunk, then switch ...
