In a language as slow as Python where even basic memory copying is slow, you don't really just have a few bottlenecks. You can optimize the most important 10% of the code and the rest of the code will still be slowing everything down. It's also a lot of work to have to rewrite parts in C/Rust and interface with Python code.
