Alex Stokes, a researcher working on the Merge with the Ethereum Foundation, told CoinDesk that the upgrade isn’t that significant but it can be used as an identifier to help with peer discovery, or finding other nodes in the network. He also said that, ultimately, developers just want the upgrade to go well. They will “do something similar on other networks, but ultimately it will have similarly low fanfare.”
