Sure - you are piling another transpilation layer on top of already slow Python.

Why not just use something closer to the metal: Common Lisp, Scheme, Clojure, Racket? Especially, use a compiled language, instead of an interpreter.

If I were to guess, it's to be able to use the all the packages in the Python ecosystem, directly. It's for situations in which Python is already a given. In fact, it's probably the case that many Python programmers can't even use this, due to being in a situation in which even the poor syntax is nonnegotiable.

I do use Racket. And over half the time I switch to Python because I don't want to author libraries that already exist in Python.

this 100%. We have some options today to run Python from CL when necessary:
