Working on a browser is not “web dev”, at least wrt how “web dev” is defined by many parts of the software community.

(Web dev is a totally cool and difficult engineering thing to do, it’s just disjoint from browser dev)

Anyway, Rust design is no longer influenced in any significant way by Servo, and most Rust contributors are not Mozillians

AFAIK no it isn't anymore, it was one of the biggest teams jettisoned by Mozilla manglement in the layoffs a few weeks ago

(So, everyone promptly hyperfocused on how to bootstrap the Rust Foundation in a hurry)
