My experience of OS packages of python libraries was pretty awful. They are out of date and it was impossible to deal with conflicting versions of a shared library that maybe two different applications needed. Switching to VMs and Docker containers helped but really this was a band-aid to deal with the fact that you couldn't depend on an OS package manager to handle this well. Packaging up Rust libraries with the OS package manager is just going to have the same problems.
