And who would assign a unique SSM G in such scenarios (viz. where an
application or content provider wants a unique SSM G) ?

The only possible issue is at layer 2. It's not good if everyone uses
G's that result in the same layer 2 addresses. Randomness might be
better than uniqueness for this.

I wouldn't completely rule out that some application may want to get a
well-known SSM group. We do have this for IPv6.
