That's FUD.  The same arguments were invoked against inheritance and dynamic
polymorphism when OOP was invented.

I think units as primitive would make a language more robust.

The main thrust of the idea is not conversion between unit systems.  That is
more of a secondary result.

The main point is that you can take the idea that a unit-area is
unit-length-squared, and abstract that across both measurement systems and
scalar representations.
