The reflective layer is still made of metal and the two layers are glued together. You have to take the maker's words on how durable those actually are.

Well, sure - but even if the reflective layer loosens, you still have the glass layer - then it would be the same as the hitachi concept: read the glass pits with a miroscope. Or add a new reflective layer.
