Sure, you do you. Personally I haven't seen anyone in e.g. the major infosec expert bubble abandon Signal for introducing mobilecoin. It's an opt-in feature, it doesn't make the message side security code harder to audit, and it's not like Moxie isn't painstakingly engineering everything to be secure from the get-go. I haven't once been disappointed in a new feature. OTOH consider Telegram that adds group video calls that nobody asked for: is it E2EE? Nope. Another security disparity to make explaining and understanding its security even more nightmarish.
