 make sense to use transients in so far as it's better than no caching at
 all?

 Not really - transients disappear without notice. Particularly I'm pretty
 sure that transients get cleared specifically on WP upgrade nowadays -
 that would leave some epic re-embedding going on which I imagine wouldn't
 be pretty for sites that embed even reasonable quantities.

 The non-guaranteed persistence of transients makes this unworkable.

 > The only other thing I can think of is that you could register a hidden
 post type, create a single post in it and use that as the fallback post ID
 to cache anything coming from a direct `wp_oembed_get()` call. It seems
 completely crazy but might be the least disruptive.

 I had wondered about child entries in the posts table (In a similar method
 to "attachments"), but not sure it helps us - there's still no expiry
 framework built in.
