Comment:

 One big problem with the current approach is is that when pasting the
 shortened URL to a YouTube video, WordPress will eventually embed it, but
 not detect that it's coming from a trusted provider. That means the
 embedded YouTube video won't work because of the security restrictions
 WordPress puts on the iframe.

 That's because the URL passed to `wp_filter_oembed_result()` is still the
 shortened URL. The resolved URL gets lost in `WP_oEmbed::fetch()`.
