I'm guessing you just aren't familiar with the landscape of professional architecture. There are plenty of good, practical reasons why this may never be implemented (business/coding/etc), but the fact of the matter is that, like I said, at the cutting edge offices Rhino is indeed used.
It didn't take me very long to look up one of the most prestigious American architecture offices:

And guess what...their job postings require Rhino.
I don't mean to demand any new feature, only to add my name to the list of people requesting, and to point out its availability in other BIM suites.
If Vectorworks considers it I will be very grateful, mostly because Rhino/Grasshopper is fun!
