Sounds like a good idea.

For example, on Hexagon, the long vectors (64- and 128-bytes long) 
normally need to be aligned to a boundary that is a multiple of their 
size.  There exist, however, instructions to load/store vectors at an 
unaligned address, although they have some restrictions that the aligned 
instructions don't.  Treating vectors as if they had to be aligned, 
while allowing unaligned pointers makes perfect sense.
