I'd be inclined to say that messages to be signed SHOULD conform to
2822. There are some 822 MTAs that produce nice clean messages that
pass through relays with little trouble, such as the one I'm using.
Fair point. Offhand I cannot think of a downside, by using SHOULD rather than
MUST.
The SHOULD asserts the importance quite clearly, and it is not as if doing 822
rather than 2822 can cause damage anywhere but to the verification of the
particular message.
