I don't think we're anywhere close to a point where transparent wrappers
(js::CrossCompartmentWrapper) will go away, or can be ignored by SM devs.
Even after Jan's changes, we'll still use them for lots of things
(including Chrome->Content XrayWaivers).

For stuff that's super edge-casey, it may be ok to punt and throw, but we
don't want to get ourselves into a situation where CCWs gradually stop
working because devs stop caring about them. They're an important
engineering tool, and I don't doubt that we'll continue to rely on them and
find new uses.
