For the case where `try` is useful over the functional form (i.e. parent's situation of having a desired Result, plus some unrelated early-returning), that ends up with nested `Result`s though, i.e. spamming an `Ok(Ok(x))` on all the non-erroring cases, which gets ugly fast.

Why couldnt you flatten it?

You have three different value cases (main value, main Err case for `?` to consume, and whatever early-return case). And the `?` operator fully taking up the Err result case means your main-result+early-return values strictly must both be wrapped in an Ok.
