Discoverability
There is a new transpiler (pycom) that's getting good engagement on reddit and hackernews.  It's written by a 15yo in two weeks.

https://www.reddit.com/r/Python/comments/w7vlim/i_made_a_python_compiler_that_can_compile_python/

Where people are comparing it to cython, nuitka, shedskin etc.

It appears to me that awareness of py14, pyrs and py2many family of work is still minimal. Someone searching google for "python to rust transpiler" will not discover this repo very easily. I don't know what the solution is. But making it more discoverable could attract more contributors.
