That is not what is documented and if you are proposing a change, I do  
not see how your proposal is useful.

The distinguishing property of STACK_BOUNDARY is that the compiler is  
allowed to rely on the stack being aligned by it.  There is no notion  
of "hardware" or "pointer" or "natural" involved; either the stack is  
always aligned on call boundaries or it is not.
