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.
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?
I'm not sure why it's not used here.
Naturally most of it isn't free beer.
