I do prefer the latter as well (and yes, happy to remove the restriction),
but I don't feel very comfortable pretending that tunneling wouldn't happen.
Of course people will tunnel stuff. But will they all tunnel it the same
way, in which case a standard could be useful, or will they each have
their own hacks? Given the vagueness about how you can tell that
something should come out of the tunnel back into the envelope, it sounds
more like the latter.
