Yes.
After their plan of starting with local iMessage and expanding later didn’t turn out well, they turned it around. Start with Matrix, add local bridges later.
The current application is based on the Beeper Mini codebase, is Matrix-First and will soon allow you to use local bridges to better preserve E2EE. As seen by some MSCs opened up by the beeper team, they are also looking into encrypted chat backups with these local bridges.
It’s not a traditional matrix client mind you, and when I say “Matrix First” I mean architecturally.
