There was a problem hiding this comment.
As noted in the PR description / commit message, I intentionally decided to always use the pattern return Hub.current.method(...), even when the return value is None. The idea behind it is to avoid accidentally returning None when the Hub method returns something else (e.g. as part of a behavior change). In other words, I find this easier to maintain than to selectively use or not the return keyword.
By construction, Hub.current is never None, such that the expression
Hub.current is not None
always evaluates to True.
This commit simplifies all uses of Hub.current, and in particular
chooses to write "return Hub.current.method(...)" for every method, even
when the method returns None. The intent is to make it easier to keep
the static API matching the Hub behavior. Without this, if a method
returns anything other than None the static API would silently drop it,
leading to unnecessary debugging time spent trying to identify the
culprit.
