Not as much as Rust has, though. I'd be hard pressed to go back to C-land now. I'm surprised they wouldn't consider a greenfield component (HTTP/3) a good candidate for it, sad.
I was going to respond to parent with "or just write it in Rust /s" but I should have known better.
For a greenfield component I do kind of agree though. I wonder does Mozilla still have the in-house Rust expertise for something like that after the layoffs?
Mozilla didn't lay off all their engineers using Rust. Just the ones whose primary job was working on Rust (as opposed to Rust components in Firefox). They still have tons of in-house Rust expertise.
