I think you have to figure that there is a difference in productivity of people who just learned Python in high school and would really like to write a computer algebra system versus people who know more mathematics, are comfortable spending 2 weeks learning lisp, spending ?? (weeks? months?) studying the state of the art in computer algebra systems as evolved over 60 years, and want to contribute to advancing the art (rather than re-programming the easy stuff). I am under the impression that learning python is a reasonable stepping stone to learning lisp.
As far as checking results for various systems, there is a category of CAS bugs that are syistem independent. That is, they occur in many systems! Sometimes they depend on secretly dividing by zero, or doing something that is invalid at a singularity. So "Maple and Mathematica and ... all agree" does not mean they are right! I think my essential point previously is that rewriting easy stuff (in a different language) typically fails to push the frontier.
