I like "usually". The truth is that outside advertisers, the NSA and
Hollywood movies the amount of content analysis done out there is very
minimal. There is known safe stuff, known unsafe stuff, a lot of probably
safe stuff, and
weird-stuff-we-dont-have-time-to-analyse-that-we-will-drop-for-now

What I'm use is any part of the spec with "use this if you want to avoid
filtering" is certain to be abused sooner than later. Just like port 443
and https encapsulation have been abused widely as soon as it become clear
it avoided lots of controls.

So is "blindly accept what you don't know". No security professional will
sign on such a proposal, since he has to justify why he let dangerous
traffic pass in case of incident.
