discussions-to grandfathering

https://ethereum.github.io/eipw/preamble-re-discussions-to/

For EIPs which were already finalized and which have a ID number below XXX?, they should please be exempt from creating a discussion on Ethereum Magicians.

For example, ERC-721 has been thoroughly discussed already and it predates Ethereum Magicians, and many of the current EIP processes. (Fun fact, 721 itself actually *set* much of how the EIP process currently runs.) Further discussion on standardization is specifically disallowed (it is frozen). Therefore it is not appropriate to require ERC-721 to open an EM thread about standardization.

Yes, this matters practically. Because I do still get a bunch of PRs against 721. Because the idiot who lead authored it allowed a bunch of (nonnormative) typos to slip in, which are being corrected over the years. And those corrections get flagged with this new rule that should not apply.

Start by reading the linked preamble at ethereum.github.io/eipw/preamble-re-discussions-to/ and compare its discussion requirement with the issue's ERC-721 example. Before changing behavior, establish the missing cutoff represented by “XXX?” and the definition of finalized EIPs. Done means qualifying older finalized EIPs are exempt while newer EIPs remain subject to the discussion requirement.
