Haha, that's true. Why would you be disappointed, though? Whether you'd call the aircraft E-3 or the E-4 in game would be dependent upon which ammo it was firing, it's not like the game considers alterations to the recoil system of the gun - it doesn't really matter in game since it's just a label for two aircraft with differences in the guns which have no practical difference in the game in terms of separating the two types. If mission builders are able to choose which ammo types are available in their mission to indirectly choose whether the player flies an aircraft with MG FF or MG FF/M - and they definitely should be able to - it's perfectly fine.
