For me, the fact that my data is inaccessible on the server is the single most interesting fact about that sync product. All alternatives would be reasons to politely decline taking part. So IF there will be compromises in the future for the scenario where users cannot back up their own key, I do hope that the current behavior will always be a viable option either. I'd rather risk losing my data through my own stupidity (been there, often enough) than pushing my browsing history (potentially sensitive) or even passwords (..) to a random service on the net.
