No, a conforming implementation is obliged to accept a strictly
conforming application.  It cannot impose its own additional
constraints beyond those spelled out in the Standard.

Hardly.  The declared object T does not contain all of the information;
the "name" data lies outside the T object.  This is as bad as the case
that Dennis objected to so far as its usability goes (apart from
linguistic correctness issues).
