You're right on the money, the emphasis in QVM is not so much on the types
that it provides, but on the ability to use QVM with types from other
libraries, of which there are many. For example with QVM you can multiply a
Maya MMatrix by an Unreal FMatrix and get a correct, type-safe result. In
addition, it lets you easily define multiple types, e.g. a highly-optimized
low level system may define its own, perhaps platform-specific matrix type,
then use QVM to enable the full set of matrix operations for it.

Yes, this does seem like a useful further development for QVM.
