However, I don't think that this means that a document not starting with
one of the listed doctype declarations necessarily does not conform to the
specification - it simply does not _identify_ itself as a conformant
document.

Yes, but just a few lines later:-

      NOTE - If the body of a `text/html' message entity does not begin
      with a document type declaration, an HTML user agent should infer
      the above document type declaration. [-//IETF//DTD HTML 2.0//EN]

HTML 3.2 and 4.0(1) all require a suitable doctype declaration for all
douments, and so do not modify this rule.
