(A lot of "boutique" TLDs are pretty dumb, so "dummy" isn't all that bad 
of a description - there's also a lot of really silly "boutique" 
products out there too.)
When I mention that the roots get the full DNS name, it's not intended 
to be a comment on whether 'boutique' TLDs reach the roots or not.  I 
agree with you that such TLDs are often done via a local addition to a 
local resolver and not via a root at all and that if that local resolver 
leaks to a root then something is mis configured.
My comment on roots seeing full DNS names is simply that if and when a 
query gets through the gauntlet of caches and resolvers - and DNS 
performance depends on relatively few doing so - in those cases the full 
DNS "question" (i.e. the DNS name being queried) is usually present in 
its entirety.
