Historic messages MUST be sent to a peer as a packet with a P2P Message code (`0x7f`) followed by an array of Waku envelopes. It is incompatible with the original Whisper spec (EIP-627) because it allows only a single envelope, however, an array of envelopes is much more performant. In order to stay compatible with EIP-627, a peer receiving historic message MUST handle both cases. Historic messages MUST be sent to a peer as a packet with a P2P Message code (`0x7f`) followed by an array of Waku envelopes.
