This is a good question, and I think about it as well. My best guess for a simple explanation: Python is very popular; it makes sense to improve performance for python users, given many do not wish to learn to use a more performant language, or to use a more performant Python implementation. Becoming proficient in a range of tools so you can use the right one for the right job is high enough friction that it is not the path chosen by many.
