All the stuff like sending emails, sending DOGE, etc. would be done on the forging node's services modules.
How on earth would you guarantee that "stuff like sending emails, sending DOGE, etc." were indeed done by forging node's services modules?
I have absolutely no reason to believe this would be safer than just using a third party gateway -- at least there I could complain to someone if "stuff wasn't done"
This is total fail.
I would never trust it
