Been trying to get this to work with v2 of the WP API that's being worked on now while moving this to a separate plugin (or function) of its own, but realizing the task is above my skill. Any chance you could help out with something like that?

while researching a unauthorized post alteration via the json-api i stumbled on your code snippet and realised i was using co-authors as well, but alas, the ancient json api that was available via a plugin https://wordpress.org/plugins/json-api/ but i'll make a note to llook at your code. My first thought was, why not either a filter or action which is adhered by co-authors plus?
