The only problem with that is it would require a separate check for all 
different types of units in use, even though each check was conceptually 
doing the same thing.

I guess it would be a simple matter for the user to derive a new 
template from quanity<Q,T> for the sole purpose of adding the static 
assert, so perhaps the library itself doesn't need to be concerned with 
this.
