Yes I'm a little unclear on what is required these days myself. I thought it had something to do with how much you said you'd do. Come to think of it, it is a little odd that EMF has many main studio wavers for most of their stations, but I remember there was one station that lost its lease on the transmitter site and I don't remember if they lost the studio as well, but in any case they applied for and were denied a main studio waver.
