Hello Mikrotik. I always wanted to have admins with special write permissions. for example user A, can just add mangle rules and user B, can just manage ppp. user C is responsible for backups and restore and etc. at first I searched too much for applying these in my radius server till I saw this useful article from CISCO:

and now, I think your later releases, Need to support this protocol, or support built-in methods in user creation.
