This kind of information is essentially an extension of part snapping information as it describes the level of freedom something can rotate/move.
Which brings use to the often discussed inclusion of such snap info into the official library. Which would be great but is very hard to get off the ground standardization wise, as it would take loads of time and effort to setup a spec and add all that info to the parts.
And also I'm still not sure it's even possible to do a universal snap info spec as the kind of data needed depends heavily on it's purpose within the software using it.
So the official spec/info would (imho) ether end up as
Or did I misunderstand you and do you only want to setup a general / standardized way for defining groups (including e.g. rotational freedom params etc) within LDraw files?

- very basic (some tools still need to (re)define extra info in order to do what they want). Although this is of course better then nothing at all.
- or extremely complicated making it very hard to implement.
