I'm wary of making such extensive changes throughout the codebase for an optional processor-specific feature of limited benefit and unproven worth.   

With each new macro and trick (Py_VARIABLE_SIZE and Py_INIT_BOUNDS), we make it harder for people to read, create, and maintain our code.  The barrier to entry is getting too high IMO.

If this were just a makefile change, it would be different.  But it touches a lot of code in ways that will be unfamiliar looking to most C programmers:

  Py_ssize_t ob_array[1] Py_VARIABLE_SIZE;   /* Looks weird and confusing */

A surprising number of files are being modified:
