You seem to be confused. The dependency chain of pycurl is python, curl, openssl. Rust has no say in this, and it won't for as long as curl touts support for 80+ platforms as a feature.

libcurl is looking to add backends which are implemented in Rust. Now, I'm sure these will remain optional, but what is a distro to do: not ship the backends in the libcurl package or have a libcurl-with-rust replacement package. (Of course, this is moot if the backends are loaded dynamically and the Rust bits can just go into a new package; I just don't know.)

curl backends are largely not pluggable; a given build uses one backend of any given type, and that's it. (Hence a lot of distros ship several curl packages using different crypto backends.)

So it's easy to avoid rust usage in curl on platforms that don't support it: build in some other choice of backends that aren't implemented in Rust. Working on embedded systems with harsher constraints is why a lot of these backends exist in the first place (e.g. the mbedtls backend), so this is nothing new for curl.
