@tyscorp I'm super interested in this feature, and I could put in some hours for this feature enhancement, but I do have one question, I see that the only code regarding each section of the API, is the JS files that are in the sections folder.
Does that mean that if one were to create the subscriptions.js section in a proper manner, that would be enough for the subscriptions API to work? Or is there more custom code needed elsewhere? (besides importing and activating the module with the createRequests binded function that is).

Yep, that's it.

Woot woot! I'll fork the repo today and start working on it.
