Here's the semantic difference between MUST and SHOULD as applied to
protocols. This is often confusing to people not immured in protocol design.
There's a more extensive explanation in the IETF document referenced.
MUSTS cause things to break if not done. Deadlocks, wrong outcomes is
what "breaks" mean.
SHOULDS mean things don't work as well if a should is ignored, but still
function. The wrong decoration appearing isn't breaking at a protocol
level.
