So, the thing specifically about ? in a language with Result is that you can read some code that uses it and not worry about what happens for Error cases if that's not currently your focus - the question marks aren't a "Look at me!" focus the way something like try-catch is.

But if you are wondering about Error cases, they are there to see when you're looking for them because that ? while unobtrusive is something you can look for.

I'm sure in most IDEs you could have it highlight ? in a "Looking for error handling" mode if that's what you want.

Note that Rust does not consider control flow to be something the core language owns exclusively, you can return core::ops::ControlFlow to say actually I also have an opinion about whether you should keep going, this can make sense for a closure or function intended to be called inside an iterator or other loop context. Some of the ergonomics for this aren't finished, but what is there is already useful where a Result would work but is ugly because your early exit scenario isn't in fact an error at all.

Error handling is no less important than the happy-path.
