The spec does not describe a superset of implementations.  It
describes behavior that contradicts what implementations actually do.
For instance, if you set localStorage.foo = false, the spec requires
localStorage.foo to return boolean false.  In implementations, it will
return the string "false", which evaluates to boolean true.  It is not
realistically going to be possible for implementations to change to
what the spec currently says.

Furthermore, we have some implementers from each of IE, Firefox, and
Chrome saying that they don't intend to change to match the spec, and
no implementers saying they intend to change to match the spec.  That
should serve to indicate that the spec is broken and needs to change,
process issues aside.

I don't see what would take a few hours to change here.  Change all
the relevant types from any to DOMString, remove all the stuff about
structured clones, and let WebIDL do the work.  That's immediately
much closer to browser behavior than the current spec.
