Again, it's an easy fix if what you saying truly matters. But something tells me you are not interested in fixing it. Other nips are not "more transparent". You can literally do the same thing in almost all of them with the same level of metadata. I know because I have debugged things like that in almost every nip Amethyst implements. Right now, my friends gaslight me on Signal and Whatsapp by editing and deleting messages as well or playing with push notification timing attacks. So, not even Marmot actually solves this.
