Not sure... "PRO" should probably be a label for "PRO" versions of something, and 16GB should probably be a minimum in that case. Lots of people doing heavy image work or video may be better served by more than that as well. Which is well within that segment.
Thats a matter of definition. Surface Pro originally was to distinguish against the Surface RT, where it made sense. Same goes for iPad Pro which is clearly not meant in the same way you are suggesting, Macbook Pro is the same. The PRO label is meant to distinguish them against their own lower tier products.
Imo the demand for 32GB RAM Laptops is pretty limited right now, which is why you usually find that in workstation laptops only.
I don't know any 13" Ultrabook with 32GB to be honest.
The issue for that is kind of like the "faster horses" vs cars. In this case, however the touchbar was a half-baked interface in trade for the lack of full touch.
