@matmarex, looks like you marked discussiontoolssubscribe API as internal. I just wanted to inquire as to the reason, and if we could get this turned into a regular API soon? This API could potentially be really useful to extensions, gadgets, and user scripts that would like to use it. Examples:
- extension PageTriage (T329346)
- gadget AFC Helper Script (https://github.com/wikimedia-gadgets/afch-rewrite/issues/258)
