No license required indeed, but you will lose some tape slots. If I recall correctly, the come in 4, so when you place the fifth (or 9th) drive you will get 3 empty drive-slots. So placing multiples of 4 in a frame is most space efficient considering tape slots.
And you have to recycle TSM to discover the changed library. Or if you don't want TSM downtime, delete the paths, drives and library and redefine.
