-1, since the expected behaviour of .T is different depending on
problem context.

The fact that this was proposed just demonstrates the fact.  If you
have a (10,5) array, .T gives the expected (5,10) array.  But if you
have a (10,10,3) RGB image as an ndarray, .T gives a (10,3,10)
array... which is certainly not what you'd expect in an image
processing context.
