 The `wp_sitemeta` database table matches exactly the format expected by
 the Metadata API. It could use it out of the box, but a bunch of bespoke
 surrounding code would need updating:

 * `alloptions` cache keys would need tests
 * Filter names would need to be carried over or deprecated
 * Network ID fallbacks would need revisiting (sometimes primary ID is
 guessed)
 * Transients, if we tried integrating them, would need... probably a lot

 I'm attaching a basic & obvious first pass at how easy this could be, if
 it weren't for all the legacy stuff. This is a big-huge task that might
 not be worth exploring much more, but I figured I'd get some discussion
 going to start.
