This goes a step beyond the three issues and also errors when dropping a user from a group that they are not in. Before, this did not error. Perhaps this is inconsistent (since addGroupMember does error if the user is already in the group), but I'm slightly cautious of raising an error when there was none before.

I was thinking about this, but I suspect, that it is not used often and while it is linked to security issues (group-based policies), it would be better to raise errors in all unexpected cases.

One more option, I was thinking about, is adding strict parameter similar to other strict uses (raise exception vs. pass, default True)

Hmm, good point. Ok then...
