So groups less than 32 are considered as bitmask, and other groups as
group numbers, and there is no way to have them consistent and behave
like group numbers?
But this introduce some problem with subscribing - if one subscribes to
group 5 and is bound to the same group it allows to broadcast not only
to group 5, and those which have the same bits set, but also to group 16
(1<<(5-1)), which has nothing in common with the requested group number.
