IMHO it is also for spotting cases where you have made the rules too strict, and maybe some backing off might make life simpler for future implementors.

This is exactly such an example. Implementors seems to have taken that SHOULD as an excuse to "improve" messages during transit (not allowed if you read the spec correctly) or to avoid enabling display of these things robustly when they do arrive (also not allowed by the spec). -- Charles H.
