metaData and playbackState, do these represent the last set value or the state that the UA is in? These may need to be async if the APIs will represent the UA's current state...

[xxyzzzq]

They represent the last set value. They are passed from the page to the UA (one-way only), where metadata is used for displaying the metadata in UI, and the playbackState is used to
display play/pause buttons and fire events for play/pause then there is a single joint button.

[travisleithead]

OK. As long as these are one-way, and represent the last set value, that works.

Should there be a way of getting the current state of the UA (in case these get out of sync for some reason), or is that not a common-enough use case to merit an API?

I don't think that would be a not common-enough use case to have it's own API.
