> there is so little Rust in Firefox that it doesn't even show up in GitHub's auto-generated count of lines of code per language (https://github.com/mozilla/gecko-dev)

There's a separate project which tracks the amount of Rust in Firefox (https://4e6.github.io/firefox-lang-stats/), and it currently has Rust at 11.7%. The other systems languages are C at 13.8%, and C++ at 26.7%.

I don't know why there's a difference to the github numbers, but maybe Firefox is developing cargo crates which reside outside the gecko-dev repository.
