ditching wallet_switchEthereumChain 🔚 

the stateful model of wallet connections where a wallet is connected to an application on a single chain feels broken

wallets are moving towards programmatic switching and displaying all assets for all chains all the time which delivery a much better UX

applications are moving towards using their own Ethereum RPC providers for public rpc requests and are only sending actions that require a signature to the wallet

given this can we get rid of `wallet_switchEthereumChain` entirely and specify the chain on individuals requests like `eth_sendTransaction`?

it's a common stumbling block for devs and adds a cognitive overhead since transactions needs to be wrapped in logic to inspect the current chain and switch
