This rule enforces that 'return await' is used in async functions.

Actually it does not

const defaultOptions = 'in-try-catch';
'in-try-catch' - do not allow return await outside of try block

Just to make sure, @ryoppippi does that matches the thing you did intend?

A more opinionated would be always as the page says

Returning an awaited promise improves stack trace information.

I would prefer in-try-catch over always

i don't mind sheathed you configure this rule. But I wanna configure this. So I registered it as a type-aware rule
