Sure, but this isn't a table top session with a dm who can change stuff on the fly.
There is the beauty ...
Nothing changed.

Except what they are from now on.
Ergo ... DM isnt required.
You have to make sure Gale the sorcerer doesn't keep paying out sorcerers, make sure Astarion isn't sneaking around in his full plate armor
Well ...
The important question here is: Did they ever?
I mean ... yes, you are corect, Gale as a Sorcerer should not complain about Sorcerers ...
But as far as i know Gale never did, so ... where is the problem?
