There is no harm in a feature if it has no annoyance/surprise.  You said
in http://debbugs.gnu.org/cgi/bugreport.cgi?bug=1757

    With the traditional behavior, if there are no buffers
    with prefix `*', you are told so immediately: [No match].
    With the new, partial-completion behavior, you are given possible
    completions that do not complete `*' in the normal way
    (as a literal prefix).

So implementing a message "[No match, type TAB again for * as a wildcard]"
will keep the traditional behavior just as you want.
