It is saying that there are circumstances other than RFC
requirement compliance that can cause interoperability
problems - like sites that add their own arbitrary
requirements.  That's just a realistic observation. You
can't use that to say any RFC justifies these additional
requirements even though the SHOULDs give best practices
to work around them.
