It should be possible to check to see if a message isForMe with only the scanKeypair, and not the payloadKeypair. There was a bug where only the scanKeypair was being used to produce the receiveKeypair, but this was a mistake. Both the scanPubkey and payloadPubkey should be necessary to produce the receivePubkey, and both the scanPrivkey and payloadPrivkey should be necessary to produce the receivePrivkey. If an online computer has only the public keys of both (and the scanPrivkey), then that is good enough to check for isForMe.
