 Every time `wp_upload_dir` is called, `wp_mkdir_p` is also called. For
 normal filesystems, this is not a huge issue, but using external
 filesystems (S3, etc) potentially means an external request on every call.

 Ideally, I'd actually like to avoid calling `wp_mkdir_p` at all there. S3
 (along with a few other external FSes) doesn't actually have a concept of
 directories; rather they're just part of the filename. Adding a
 `upload_dir_requires_creation` filter to `wp_upload_dir` would help with
 this, as plugins could then switch this off if they know the underlying FS
 doesn't need it, or they already handle it themselves.
