I went out and checked again, and it definitely is a foam block glued or taped in place. Manufacture date is 8/11, and it apparently arrived at the dealer the first or second week of September.
What you say is most encouraging, though, and the first such report on JG. It's not a slam dunk to replace the existing long piece of hard plastic holding the block with what is apparently a new one with the molded snow blocker, but it could be replaced even by an owner. Moral of the story is not to bring the old block into the repair shop should it be starting to work its way loose; just yank it off, put it aside, play dumb, and have the dealer install the new hard plastic part.
What would help is to have a photo posted of the new setup, if anybody comes across one. If nothing else it would give us something to show to doubtful repair shop foremen.
