I fully agree with you that NSID (RFC 5001) is great and Google should
really deploy it. However:

I assume that Google wants also to be debuggable by people who work on
inferior operating systems, and have no dig. Hence this trick. For
instance, L.root-servers.net has both NSID and a special name,
identity.l.root-servers.org (see RFC 7108).
