I think most people have misunderstood these changes. Drive letters are not removed, but the option "Show drive letters" in folder options is removed. By default, that option is enabled, so the drive letters will be shown, now if you want to disable them you'll have to go to the registry.
Just like "Hide protected OS files" is enabled by default, it will remain like that, if you want to show them, you'll have to fiddle with the registry instead of just changing an option.
