If by never even read you don't include attaching a debugger to solve an issue. 1,000 global mutable variables would make debugging anything an absolute nightmare.
It's a useful term, just like "clickbait" was 10 to 15 years ago (and still is). Trying to police other people calling it slop is reminiscent of Microsoft autobanning anyone using the term "Microslop" on their Discord, it's idiotic language policing and I'm not going to do it, simple as.
Because it hasn't been released yet (at least not outside of some unstable branches). You can find some criticism of the actual slop here though: https://old.reddit.com/r/rust/comments/1t4033y/buns_rewrite_...
