I don't think that is a disadvantage of bitboards or a reason not to like them.
That seems about the same as not liking a 10x12 board representation because 120
is not a power of two. So what?

It is very likely that the compiler will align that 120 bytes to 128 bytes
anyway. Probably if you only used 60-bits for some game, the compiler would pad
the 60-bits with 4 dummy bits.

Besides, I have never seen anything that can be done only in bitboards or only
in an array based representation. They are each just a way to model a chess
board and require different ways of thinking.
