I'm really not worried about it... I just don't want "performance" to be
used as an argument for a given design decisions when the proposed change
won't actually make things faster.

This would definitely be faster. Faster yet would be doing a
PyNumeric_Check (or PyNumarray_Check, or whatever they're called) and just
cast the pointer to the underlying representation. If you must go fast, go
as fast as possible...
I'd rather we didn't add a lot complexity to the array protocol to just go
at a medium speed.
