This. When tech leaders look at Rust as a solution for legacy products and services - then see Crab grab - it makes them think the ecosystem isn't mature enough for their 25+yr old platform.
And you are saying that multitude of C compilers make C less mature ?? You are literally saying "tech leaders" use some kind of reverse logic :) Maybe Mozilla isn't Oracle but "trademarking" lang name is just Java-like move.
It's more likely to be removed if the effort failed (which it seems to be) than it was to be added in the first place.
