I wasn't sure if we just thought there wasn't much utility in it or if there was a technical obstacle.
I would think that would be easier to build than the other aggregates since as you add more geometries it shrinks and the current aggregate state is always the result of the previous state plus new geometry (so no need for an accumulation function or a final state function) and if you ever end up with a geometry collection, you short-circuit out.
