Ah, I meant "stack traces" in the system sense: Imagine a really deep chain of #[wherr]-marked functions. If I understand the crate's behavior right, when an error occurs in that case, you're effectively constructing a stack trace as that error bubbles up through `?` operators. Now, maybe if the functions return something like Result<_, wherr::Error>, you could collapse those traces, but if you're returning Result<_, Box<dyn Error>>, that isn't possible (barring macro shenanigans).
