I'm corrected (I hate those "standards" which are not even available
online.)

I don't see why? "Local" or "private" domain names leak, yes, that's a
fact, but it happens whether it is a TLD or not. At least, with a
subdomain, the risk of the full query going to the root is lower. (Of
course, everyone should use QNAME minimisation but it is another
story.)
