Emphatically disagree.   We aren't the protocol police, but the idea 
that local policy can degrade interoperability at will and still comply 
with the standards makes no sense.

Spam filters are a good example.   Poorly chosen spam filters are the 
primary reason that email has become so unreliable.

I believe our job as protocol engineers is to define protocols that will 
work reliably without operators needing to second-guess them, not to 
support cargo cult practices that degrade interoperability.   If 
operators think they need to second-guess the standards, that's 
something we should take notice of - maybe we as engineers haven't done 
a good enough job at designing and maintaining our protocols.
