Could you

1: give us some background on the discussion that resulted in SHOULD
instead of MUST, and

2: consider adding explanations of when it would be appropriate to not do a
SHOULD?

For 2, above, there's a great difference between "SHOULD do x unless
there's some reason that it's impossible in this implementation" and
"SHOULD do x unless you don't happen to agree with it."  I'd like to try to
tease those apart.
