First point - yes but there will be more incentive to roll a rommie/kdf - than a normal KDF for the extra potential.
And you can just as easily say that there's no incentive to roll a Fed because a Rom gets all the Fed missions and extra potential too. So I guess that means:
THE FEDS ARE FACING EXTINCTION!
STO is about my Liberated Borg Federation Captain with his Breen 1st Officer, Jem'Hadar Tactical Officer, Liberated Borg Engineering Officer, Android Ops Officer, Photonic Science Officer, Gorn Science Officer, and Reman Medical Officer jumping into their Jem'Hadar Carrier and flying off to do missions for the new Romulan Empire. But for some players allowing a T5 Connie to be used breaks the canon in the game.
