I see the issue. The challenge here is to be able to support removal of
members in (org unit) groups, at the same time as supporting incremental
additions to a group. What I mean is, if you for instance want to remove
all but one member for a group, then the best way is to simply include that
single member in the message and none else. This conflicts with the desire
for convenient additions of members to a group, where you must post all
members. I think we need to add a new method for this. Feel free to suggest
what would be most sensible.
