I guess there's a question as to why the poly types have been omitted.  We don't need to be that precious about the header containing only the bare minimum types that are needed across NEON and SVE.  I've seen circumstances where users have wanted the types but nothing else.  I know this is not the goal of this patch but it's a step in that direction.
