Thanks Carlos for that timely information as Lord knows, the last thing
Apple wants is to play nicely with Android messaging (which isn't even a
guess on my part because I read the internal emails published during the
Epic court case deposition where that's essentially what Apple execs said).

Looking up MLS:
 <https://messaginglayersecurity.rocks/>
 "Messaging Layer Security (MLS) is an IETF working group building 
  a modern, efficient, secure group messaging protocol."

Q: Should I use this right now?
A: Yes! The protocol has been approved by the IESG and has been 
   published as RFC9420. There are several implementations, 
   of which some are open source.
   <https://github.com/mlswg/mls-implementations>

I looked for an Android messaging app which supports MLS but it might take
a while as the Skyica App Finder isn't working lately for some reason.
