Note that definition says "arguments". I'll have to assume it says that
for a reason. So there shall be zero arguments, if there are no
positional parameters, and echo shall print nothing (except for a
newline). I don't think you can argue with that.
Let me take this opportunity, as a devil's advocate, of another possible
generalisation of "$@" to "foo $@ bar". I would argue that
sh -c 'foo() { printargv "Testing ${@} fnord"; }; foo a b'
should print
Testing a fnord Testing b fnord
and there is nothing in the definition that will contradict this
interpretation.
