MLS is designed to support that use case, but the spec to actually intercommunicate between services is still being developed by the MIMI group. MIMI is the logical but entirely optional extension of MLS.
I don’t think carriers will want random chat apps to send messages for free to their infrastructure for spam prevention alone. Companies like Element and Wire are probably going all in on this, but Signal doesn’t even want you to use clients they didn’t compile, let alone federate between services.
I believe WhatsApp has chosen to license its API in a documented fashion rather than implement a cross platform messaging protocol after they were forced to open up by the DMA. That said, there are a bunch of Facebook emails in the MIMI protocol discussions, so at least one of their messengers may still end up implementing MIMI when it’s finally finished.
