Any time two CAS differ in their capabilities, you will have to choose for
the standard the least capable.  Otherwise you must distinguish between them,
and once you do that, you have no standard.

Imagine a CAS that only knows about polynomials.  How do you standardize
its response to a question that requires rational, algebraic, logarithmic,
exponential, trigonometric, etc. functions.
