A checklist for things to check before merging a chain PR.
If the PR contains explorers claim to adhere to EIP3091 - check if they really do. If the PR contains icons:
ipfs getall icon CIDs- check if the size of the icons you got match the size given in the PR Check if a PR does not remove a chain - chains cannot be re-moved - only deprecated (to protect from replay attacks) Check if a PR does not assign a chainID to a newer chain (something like ethereum-lists#1750)
If anyone has ideas on how to automate these things in CI - PRs welcome!
