There won't be any exceptions for RB.
Yes, there was a case with ships being re-researched getting rewards by default, with the ability to double reward per ship, but that was due to RB being only recently announced and short span of time being given.
This situation is different - people should be more familiar with RB, and there's enough time for active players to finish getting their research bureau bonuses and make an informed choice whether to start a new one or not.
And I may add that RB aims at players who need more challenge and more goals in the game, and have a lot of ships - it even doesn't appear until you have 5 T10 ships.
