Hi Andrew,
thanks for the clarification. Makes me feel more comfortable with what I would have preferred. Until that´s improved in software - what do you recommend to monitor in order to verify the forest is not going to split into individual trees? 
Thanks & Best regards, Joachim

Yes, it should use itself as the DNS server, once the initial registration work is done.

We know this area isn't ideal, and we are actively working to improve it.  I expect Samba 4.5 to be much more sensible in this regard, given the patches I've seen from other Samba team members and the work my team at Catalyst is currently doing for our clients.
