This is one of those things that kind of bugs me about, say, OsStr / OsString in Rust. In theory, it’s a very nice, principled approach to strings (must be UTF-8) and filenames (arbitrary bytes, almost, on Linux & Mac). In practice, the ergonomics around OsStr are horrible. They are missing most of the API that normal strings have… it seems like manipulating them is an afterthought, and it was assumed that people would treat them as opaque (which is wrong).
Go’s more chaotic approach to allow strings to have non-Unicode contents is IMO more ergonomic. You validate that strings are UTF-8 at the place where you care that they are UTF-8. (So I’m agreeing.)
