It's real-world Python. Why do you think stuff like SciPy are so popular?
Rather real world Fortran, C and C++ with Python glue code.
Just like Tcl, Ruby or whatever scripting language with the same glue code would get out of it.
Two languages to learn. Two languages to support. Two development environments. Two build tools. Two CI/CD pipelines. Two testing infrastructure. Two sets of code and security reviews.
Double the complexity and for what exactly ?
