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.

Doesn't matter if signal is secure if nobody uses it. None of my friends are willing to use it because of the lack of features and horrible ui/ux.
