 > I'm confused. Can you provide a use case for that?

 We want to improve the experience of uploading media when you’re over
 quota. Part of the task is omitting the upload form for users who are over
 quota. In core, when the quota is exceeded
 [https://wpcom.trac.automattic.com/browser/trunk/wp-
 admin/includes/media.php#L1332  the form isn’t displayed]

 However, on WordPress.com, `is_upload_space_available()` always returns
 true, because the `upload_space_check_disabled` option is set to true. All
 of these functions that try to calculate filesystem disk usage don't work
 on dot com as we check/store that information differently.

 tl;dr: the purpose of the filter is to be able to hide the upload form
 while keeping `upload_space_check_disabled` set to true.
