I'm fine with this being a SHOULD , fwiw. I was just repeating the original

receiver is always at liberty to feign igornance.

I don't see the interoperability or security issue that would make this a SHOULD. The order given shows the signer's preference; the verifier MAY do whatever it wants.

...which goes to show why having two different formats to say the same thing is inherently flawed.
