I wouldn't actually characterize "Wordle in Rust", "xyz in Go", etc for the sake of learning a language as "rewrites for the sake of rewrites", though - I would characterize them as rewrites for the sake of learning and there's nothing wrong with that. Coming up with a new idea and implementing it with technology you don't know is a lot harder than implementing an existing idea. Blog posts about them are often interesting simply because you get a new perspective on the tools you use frequently. I'm talking about the types of things where a rewrite is done not for the purpose of learning, or because a specific set of issues is identified in the existing project, etc...but because "this language is better so I'm rewriting X in it"
