No. That's not how RFC 2119 MUSTs and SHOULDs are used. MUST NOT means that doing so is known to cause harm or interfere with interoperation. That simply isn't the case here. We can imagine cases where having redundant Sender information might cause confusion, but we say SHOULD NOT because there may exist valid reasons where the behavior is acceptable.

Agreed.  Thank you for the clarification.
