The NIP-12 standard, or the Non-Fungible Token (NFT) Standard on the NEAR Protocol, defines a set of guidelines for creating, managing, and interacting with NFTs on the NEAR blockchain. The standard includes a number of fields that can be used to describe an NFT, including a metadata field that can be used to store additional information about the NFT.

It sounds like you are proposing to add a new feature to the NIP-12 standard that would require the use of a filter for a specific key, and that the subscription would fail if this filter is not set.
