[TimDaub]

• [x] Consider name change to "Account-bound" tokens
• [x] In rationale, add the following about caveats of the implementation
  • [x] tokens are essentially account bound and cannot be reclaimed in case of e.g. a wallet rotation
  • [x] highlights that account-bound property can be circumvented using contracts
• [x] Re-edit "Rationale" section
• [x] Address @will-holley feedback. Implement suggestion from Eth Magicians: https://ethereum-magicians.org/t/eip-4973-account-bound-tokens/8825/19?u=timdaub
• [x] Address @iainnash's feedback: Write about the spec's neutrality towards admin transfers/migrations
• [x] Address @SamWilsn's feedback on GitHub PR
• [x] Add "Raphael Roullet (@ra-phael)" as co-author
• [x] Address comments in implementation from call with @ra-phael from 2022-05-04
• [x] Address ETHMagician's feedback from @MicahZoltu about encouraging users to rotate keys.
• [x] Address criticism that reassignment can be censored
• [x] replace "non-transferable" with "non-separable"
• [x] Address problem: Some voting implementations like snapshot org's EIP-721 relies on balanceOf interface: https://github.com/snapshot-labs/snapshot-strategies/blob/master/src/strategies/erc721/index.ts
• [x] Mention implicit account-binding in contracts and ABTs as a normed alternative
• [x] Work on on-chain disassociation
  • [x] update reference implementation to latest disassociation changes: https://github.com/ethereum/EIPs/pull/5136 https://github.com/rugpullindex/ERC4973/issues/5
• [x] Narrow scope of contract by introducing WoW Thunderfury item in motivation section
• [x] allow emitting multiple Transfer events in one minting operation
• [x] should sender also be able to revoke an ABT at any time?
• [x] Wait and help fix: https://github.com/ethereum/EIP-Bot/issues/93
• [x] remove underscore convention from input names
• [x] Consider using permit like functionality that keeps the minting-allowance off-chain and then allows lazy minting on-chain
• [ ] Test-mint an EIP4973 token and check what popular wallets display
• [ ] Test-mint an EIP4973 token and check if indexing of event signatures is practical enough using even Transfer for popular wallets
• [ ] Consider adding a function collectionURI, what aboutfunction name function symbol?
• [ ] Reintroduce from field in events
• [ ] add a recommendation that tokenURI shall ensure metadata content integrity
• [ ] Implement safe... variants of burn and mint, introduce optional ERC721Receiver extension for contracts

• should sender also be able to revoke an ABT at any time?

No, because this isn't what e.g. would happen in WoW with a soulbound item.

• allow emitting multiple Transfer events in one minting operation

Implementers of the standard can do as they please.
