These scalar modes are redundant I think, can we forbid them?
There are 40+ scalar modes that are not used.
Those are fairly standard complex modes. Those are unlikely to go away.
Some of those might be redundant with 2 element vector modes, but I'd
hesitate to do something like using CDI to represent a 2XDI vector.
