I found the documentation of the "uncertainties" package. It is not as powerful as using the general expression I provided above inside Sage because there is only a limited set of analytical derivatives the package knows about and then it uses a robust digital differentiation scheme for other functions. Thus the package only provides numerical derivatives. Since the analytical expression is important to scientists working on novel measurements, this would only be useful for routine error propagation of standard measurements. Sage has a finite set of analytical derivatives as well, but it is pretty extensive.
That said, integrating the uncertainties package into Sage would probably be useful to many scientists and engineers.
