Social Media URI Propagation Event

A nice use case of preferring URIs over raw text content is where e.g., CAIP-19-style URIs for NFTs could be used to curate NFTs. E.g. someone could also release their latest music NFT tracks in a release club or post the latest crypto kitty using CAIP-19: eip155:1/erc721:0x06012c8cf97BEaD5deAe237070F9587f8E7A266d/771769

Is there a reason contracts wouldn’t just call poster rather than implementing this function?

With regards to EIP-3722, I think I’m mostly confused about using JSON and its format in string content. So my idea was to distill it and give any implementer the chance to build their own emission contract business logic instead of having a single repository. Instead of posting content directly, rather I’d prefer if users posted a URI or even better a content ID from a network like IPFS.
