I find this proposal very applaudable, especially as I had been calling out not standardizing mint and burn in a previous post on this forum: EIP-4973 - Account-bound Tokens - #129 by TimDaub
However, I think the proposal would be stronger if it rigorously created separate documents for EIP-721, EIP-1155, and EIP-20’s mint functions. E.g., I have no knowledge whatsoever about EIP-1155 and only very limited knowledge about EIP-20. Hence, although I’d like to help you review and improve the document, my knowledge is mainly in EIP-721 - but I don’t feel like being able to make suggestions for the lack of the other standard document’s inclusion.
Still, thanks for taking this on, I think it’s an important step in the right direction!
