I never suggested that.  What I suggested was that they SHOULD be
performing consent checks.  The fact that they don't is what I would
term a "legacy requirement".  I don't think that we should be
extending this exception to any other entities.

The only reason that ICE-lite gets away with not sending checks is
that it trusts both the signaling entities and its peers.  That's
dangerous.  We interoperate with ICE-lite only because doing otherwise
would exclude more entities than we are willing to exclude.

The current text is fine.  It opens a minimal hole that acknowledges
the existence of the bad actors, but doesn't attempt to bestow any
kind of validity or legitimacy on them.
