Will 2 limited members now be able to talk with each other ?

If this change makes the MC requests to the full partition for limited
members, that seems correct (as limited MC groups are useless). If it
causes/also causes the UD AVs used to send to have their limited PKey to
be promoted to full member, then that is not fine. Does it do the latter
as well as the former ?
