I really wouldn't worry much. Over the last decade of rust, very few of the articles exploring new syntax have turned into anything controversial by the time they were merged (I can't even think of big rust syntax changes other than `impl T` in arguments etc). The singular example really is async/await and, having been quite worried about it / against it at the time, it was really nothing to be concerned with at all.

let-else was a more recently added new syntax

Indeed, but it hardly seems controversial or major. It's sort of just an extension of existing syntax, similar to `impl Trait` in argument position.
