Can we atleast make it backward compatible. It's broken right now.

It's not broken. That's the way we add any other content to posts in Nostr. I am just adding a NIP94 event.

This is superior in many ways I understand but experience is broken.

Only because some clients have yet to implement NIP-94. That's ok. We saw the same things with zaps, long form contents, polls, which other apps also don't see.

Is it possible to maintain backward compatibility without breaking the user experience while also implementing new cutting-edge features I mean take a example of this post. On Amethyst it seems like Will posted this picture.
