I agree but right now wallets not using stealth will only lose metadata,
not coins, if their computer crashes and they have the seed backed up.

But if a user wants to upgrade to stealth, they then risk losing metadata
AND coins if they either didn't manually back up after every transaction or
use a centralized cloud backup service.

That's if OP_RETURN is not utilized for storage.
