Obviously, commercial organisations have a long track record of developing and supporting programming languages.
Enterprises tend to invest in <5 year projects, I've noted, and 5 years is a hell of a long time for an extended investment.
This is inaccurate, the URL parser never was and still isn't in a released Firefox.
The first Rust in a released firefox was the mp4 metadata code.
It's worth noting that in those 7 years Servo advanced a lot, which meant that the Stylo project didn't have to rewrite a style system, just take an existing one and polish it. (This is still a lot of work, but not as much)
A good job. Most commercial PL efforts kind of suck. There are a small number of exceptions, and Rust is one of them.
You could argue survivorship bias but that applies to Rust as well.
