NIP-31!!!

Imagine if the template your app creates even generates a gorgeous card for the NIP-31 opengraph and your not-9802-supporting-client just renders that.

Context was the missing piece to make this work and NIP-31, specially with the template idea, provides all the context, and with NIP-89, you can even find how to consume the unsupported content (i.e. if it's a podcast open fountain, etc)
