We can't standardize the keychain until we are done modifying it. Right now, we are working on amazing noise-key delegation capabilities. fwiw i don't really believe that "standards" and "specs" are the same thing. What is standard is what people actually use, so we can't establish a standard until more people use it. In the end, if any dev wants to build with Pubky, we will assist them, and if we break anything we will provide them with the same solutions we need ourselves. It's all open source and tons of work to do this right. Don't let excuses scare you. It's Nostr 2.0, and you are missing out.
