 > Which would be good option?

 I suggest option 1: augmenting `postMessage` transport with selective
 refresh. From the [https://youtu.be/ikW8dfaOPng demo video], you can see
 this has the added benefit of allowing a JS implementation to do an
 approximate instant preview of a setting change while waiting for the Ajax
 response to return with the actual rendered contents. The JS preview logic
 is not required here.
