Ok, I get it.Rust is cool af.
I'm a programmer who has been programming since around 1980; self taught in just about everything except assembler and TRS-80 BASIC, and at 62 still a productive professional programmer programming in python.
I've just come from PyPI.org, where I find that many packages listed there are drop-in replacements for python packages written in Rust, or new bits of work written in Rust but wrapped in a python binding.
Lets be clear: I am not a Rust hater. I've started taking an online course to learn some Rust, because the products of the toolchain are undeniably amazing.
I'm finding the language to be more than a bit difficult, however, because like most new and effective advances in computers science, its very different, and that makes it challenging.
What I am finding I don't like however, is the behavior of the community. Just because you *can* write rust code that will e.g., fit into the linux kernel, or be easily wrapped into some sort of binding, doesn't mean I want to discover that my python package repository, full of lovely python programs, done pydantically, and all according to the PEPs we know, love, and depend on, to be supplanted with a bunch of python wrapped rust code. Its unfriendly, unnecessary, and most importantly, dilutes the effectiveness and maintainability of the index and the code found there.
By all means, write Rust apps, if you're able.
Just keep them out of my python 
reposititory.
Just my 0.02$
To reiterate: I have nothing against any programming language. They're all useful in some respect, yes ALL of them.
I just want my python repository to be pure python, with very few very notable exceptions.
