It's not as bad as you might think. If someone were to add 
CompositeUserData to OSG, they'd need to port all (internal) OSG code to 
use the new system. External apps that use UserData would not be 
compatible with the new system until their authors take the time to 
port, but that's not really a problem, as it's no worse of a situation 
than we have right now.

I'll also add that this would not be the first time OSG has had a 
non-backwards compatible change (parameters to the draw callback that 
changed in the 2.0 release being the other change that comes to mind in 
recent memory), and everyone lived through that :-) .
