By the same token, you can have multiple-of-1 (i.e. arbitrary positive integer - is there a better name?) return codes, and shift left by 2 or 3 bits as appropriate. But it may be that the existing convention to some extent discourages very sparse return code domains, which makes the branch or address table scheme largely unusable.
