Should muted be included in the MediaSessionAction enum? e.g., many browsers have an option to 'mute' a tab--is this a scenario that should be supported?

Currently, we are mainly targeting mobile platforms. On mobile platforms, we should respect to the OS volume control, and controling the volumes of the media elements on the page should be rare.

For desktop, I think "muting a tab" should be still be handled by the UA instead of the page, as the page might ignore the muted action, then we need UA to have fallback steps to force muting. Also I think muted is less useful given that we already have pause.

I think I agree with that. The only reason that a page might want to react, is to stop playing the media, which might allow the media stack to be unloaded in the browser, saving memory on mobile devices... but then the muted state goes away (as it's now in a stopped state) and that transition does seem a bit forced.
