The last time I read the standard for shell & utilities completely (which
is admittedly a few years ago) I was implementing a Posix shell myself.
And "$@" should expand to _nothing_ if $@ is empty, not "".

Test with:

#! /bin/bash

if [ "$LOOP" = 1 ]
then
        echo "\$@: $@, \$#: $#"
        exit 0
fi

export LOOP=1
$0 "$@"

Results:

bash: $@: , $#: 0
ash : $@: , $#: 0
zsh : $@: , $#: 0
