Depends on how many workstations and server are on this site.

I would demote it and promote it to a RODC and GC server. You don't want to congest the slow link with authentication and replication tasks.

If it's not a dc there would  be no replication
Correct but RODC would only do a initial sync of AD and after that only AD changes/updates. You can setup RODC password replication for users in that site to save even more on bandwidth and in a event that link goes down.
