Not at all, consider Unit type declared modular because it has to be used
as a discriminant. At the same time Unit is a composite of powers for mass,
time, current, temperature etc. One would like to have it indexed (viewed
as an array or as a record).

Another problem is that you cannot make everything Controlled without MD.
Because otherwise you will permanently run into problems with primitive
operations of multiple types, multi-methods etc.
