We're technically not setting the ForwardRelayerAddress anymore, I'm wondering if we should have a different setter for this use case specifically.

Yes maybe we should name it something else?

Is this mapping only used for async acks? Maybe the function name should take that into account? SetRelayerAddressForAsyncAck

I went with SetRelayerAddressForAsyncAck & respective getter fn

@AdityaSripal Can you remind me again why you don't want to error here? I'm throwing an error below if not found, wondering if you want to omit this also?

We should throw an error here since that should never happen.

We want to ignore the error here.

This is because its possible that relayer has not registered counterparty address. If they haven't then, we just write acknowledgement with an empty relayer address.

We don't want to prevent writeacknowledgement from succeeding because relayer hasn't registered counterparty address.

This effectively means that recv_fee will get refunded and not incentivized, but that's the relayer's fault
