Having used Python from a shared network mount (NFS, GPFS, Panasas, Lustre) and waited for it to stat 10 thousand files over the network just to start up (thanks, pkg_resources), I also wonder why a VCS would be implemented in Python.

(In fairness, Python isn't the only culprit, Cargo also stores it's index as directories and files and would probably be much snappier it it used sqlite).

side talk: AFAIK, cargo is only needed for compiling, not for running the application, right? Slightly different than the Python story...
(Disclaimer: I never wrote Rust code but use Python 3 in a few projects.)

That's right.

pkg_resources is infamous for this (there's an open bug, but no clear path to resolution). Luckily, not every Python script uses it.
