There's already been movement to deprecate using float128 as the name for
machine-specific long doubles. This just gives even more reason. If/when
someone adds __float128 support to numpy we should really just call it
float128, not quad128. (This would even be backwards compatible, since
float128 currently gives no guarantees on precision or representation.)
