In its original usage in RFC 1122-1123, SHOULD was applied where we could
imagine relatively unusual or extreme conditions where the MUST might not
apply.  But the intent was that anyone who overrode a SHOULD ought to
be able to present a credible argument to his/her peers to justify this
deviation.  In other words, you had better have a "DAMNED GOOD" (technical
term) reason for it.
