We're actually getting some work done on Maps v2.x right now which we
hope to "forwardport" to v3. Mostly polygon related stuff - smart
labeling, hover, additional layers, autocenter, etc.
I find it somewhat odd you are adding to this obsolete branch (at least from a dev perspective), and recommend against it. You'll just going to get yourself into tricky porting work for 3.x.
