Firefox has been using Rust since 2017 and about fifth of its code that was previously in C/C++ has been written in Rust (see Oxidation sub-project).

I'd expect slower cycle for Linux than Firefox. I think this would be likely truth for operating system with decades of legacy (e.g. BSD derivatives).

This makes me think that making any conclusions after two years is simply not a pragmatic mindset.
