As programmers, is it not our natural instinct to create a ChatSystem and MailSystem on top of a GenericMessageDeliverySystem? When did we stop doing that? Creating a brand new GenericMessageDeliverySystem for each purpose comes with substantial costs. We don't reinvent the Internet to create WhatsApp.

What generic message delivery system are you talking about, though?

SMTP is optimized for the use case of email; XMPP is optimized for one-to-one instant messaging; Matrix is optimized for "Slack-like" chat.

I highly doubt that these three use cases are similar enough to warrant introducing an additional common protocol/layer.
