They all have the capability to support a UI where you type a message, hit send, and the message is delivered. This proves it’s possible to make and support an interface that hides all the backend complexity. If they don’t expose the same functionality through an API, it’s because they don’t want to, not because it’s too hard.
I’m sure there will be some features that aren’t fully supported across messaging platforms, but for basic use cases like sending a text or an image, there’s really no excuse.

It would certainly be a technical challenge. But I think the utility would be very high. In my experience, it’s difficult to convince people to use an app like Signal if they can’t use it to communicate with their Whatsapp contacts (etc.).

It would probably just use RCS as the backend and have some different functionalities, they could easily just highlight “this person isn’t using Signal so chat features are limited”. Hell, Signal had exactly this when they made the app work as an alternative SMS client. They removed that feature, but it existed previously.
