I don't think it's bikeshedding. It does seem to be contributing to the dogmatism I'm seeing from the Rust community here, and this community reaction is a huge problem for Rust. So it matters.
Bike shedding is a structural description, not a value judgement. Itβs about technical complexity, and changing a keyword is one of the most minimally complex bits of language design.
My point isn't to argue over the definition of bike shedding. If the name of this keyword is contributing to this undesirable community outburst, then its name matters, and discussions about its name are important. That's all I'm saying. If that's what you originally meant, then we are on the same page :).
