Severity standardization - Protocol does not support CryptoPunks

[trust1995]

Cryptopunks do not conform to ERC721. Since the majority of NFT-centric protocols use the ERC721 interface to interact with NFTs, they do not support CryptoPunks without some additional wrapping. It is a very common report to see in NFT related contests, and has in the past mostly been judged as QA:

Nibble - QA
Blur - QA
PartyDAO - QA
Cally - QA
Foundation - MED

Note that in the Nibble discussion, the judge which was the Foundation sponsor remarked that it was too generous to Ack as MED.

It seems like, by our severity guidelines, the issue is QA level. Punks can be wrapped externally and treated as ERC721. Also it sounds more like a feature request than something that is automatically assumed to be available.

Feel free to post feedback below.

I agree 100% with this. This issue should be QA.

Low because you can wrap them
