I do believe (but, though I work at Mozilla, I don't work particularly close to the relevant team) that our support team regularly gets help requests from people who have locked themselves out after e.g. wiping their device, and we can't help them recover their data. It's a hard balance to strike between usability and privacy, though Google obviously guides the user more to the never-lose-my-data end of the spectrum that also happens to give them more insight into what the user does.
