Regarding the previous discussion, while I can see the issue of nobody wanting to have a mint-open EIP721 token because today it’s obvious that this functionality has to be permissioned, I’d ask commenters to refrain from discouragement. In case it is truly useless to have a document standardizing minting and burning, I guess this work will simply be irrelevant and forgotten - but won’t do any harm.
Still, as I’ve already mentioned in EIP-4973 - Account-bound Tokens - #129 by TimDaub, I’m skeptical of both mint and burn not being canonically (at least optionally) available. I’d see this effort as explorative programming. In my own experience, merely expressing one self can spawn new ideas elsewhere, so I can only encourage you to continue working on this.
IMO a problem that is potentially solveable is this: When everybody can call mint as much as they want, how can EIP-721 tokens have value?
