You're right - it doesn't... I misread my old code... I missed my own
packing/unpacking of the coordinates from/to Points (read them out into a
flat array, broadcast(), recreate Points).
So - never mind. I guess I'll do the same thing again for now.
How tough would it be to make this work with Point? Or should I be using
allgather_packed_range() for this instead (would that work as is?).
