The point of splitting is not to splinter, but to allow those who don't
wish to upgrade immediately a chance to think about it for a year or so.

The 2.2 in this case would be a dead end. Mods to 2.2 probably would
still be applicable to 3.0, as the only thing to be changed is the
resource management interface (though any changes involving that layer
are going to be a bit of a pain). In fact, 3.0 could be virtually
identical to 2.2 but for the interface (using macros in 2.2 for old
calls). The point is that the old interface stops at release 2.2.
