Even if one argued that "Testing ${@} fnord" is a meaningful
substitution, then according to the above definition, it should produce
zero arguments if there are no positional parameters. Yet,

    sh -c 'foo() { echo "Testing ${@} fnord"; }; foo'

produces (on 3.0)

    Testing  fnord

which I must consider a bug.
