addEthereumChain Remove 'May not specify default MetaMask chain' error

[RomanG11]

I'm trying to make something like change network chain request. Everything works correctly, but only with new network IDs.I don't understand the reason why you did this check. If you could remove this, many developers will thank you.

if (CHAIN_ID_TO_NETWORK_ID_MAP[_chainId]) {
return end(
ethErrors.rpc.invalidParams({
message: May not specify default MetaMask chain.,
}),
);
}
