Thank you. I think if this becomes standard then existing clients can query those additional data (currently kind 9978) using certain tag (currently d tag) limited to certain pubkey filter (currently with my bot pubkey). Clients can give certain filters option in their settings for users to be picked (language, category, etc). If there are other data providers then they can pick other data providers (other pubkey) so users have freedom to choose whatever algo/filter method they want. Before that, i will check whether better use NIP-32 implementation or stay with current implementation. 😅
