Comment (by SergeyBiryukov):

 Replying to [comment:18 garrett-eclipse]:
 > I'm ok with it off, just see it as a way to link the two together in doc
 spaces and indicate the function can now behave differently than expected
 if anything has hooked into that filter.

 I think they would still be linked the same way that `username_exists()`
 currently links to the `username_exists` filter in the
 [https://developer.wordpress.org/reference/functions/username_exists/#related
 "Uses" section].

 I'm not strongly opposed to adding it to the function, it just seems like
 we don't generally do that for new hooks, as that partially duplicates the
 hook documentation.
