I am closing this pull request because we are in the process of separating EIPs and ERCs into distinct repositories. Unfortunately, as far as we are aware, GitHub does not provide any tools to ease this migration, so every pull request will need to be re-opened manually.

As this is a PR to create / modify an ERC, I will kindly ask you to redirect this to the new repository at ethereum/ERCs. We have prepared a guide to help with the process.

If there is relevant history here, please link to this PR from the new pull request.

On behalf of the EIP Editors, I apologize for this inconvenience.
