In 0xB10C/mainnet-observer#24 (comment) noticed that some of the pools were only identified by their coinbase tag and fixed some up in #114. However, it's not clear if all addresses are up-to-date now and if there are old ones missing.
As identifying by address is preferred over identifying by coinbase tag (coinbase tags can easily be faked), the addresses should probably be kept up-to-date.
Probably best to write a simple tool that check the identification status (known/unknown, identified by tag/address) of recent blocks. Could use https://github.com/0xB10C/rust-bitcoin-pool-identification for it.
