"$@" vs. nounset

Hi, I like using nounset for stricter scripts, but an annoyance is that anytime I use "$@" and it's empty, I get an error, when (to me, cognitively) it is not "unset" (as in someone *forgot* to set it), it's just an empty, which is a common case (IIRC, in bash, variables set to empty arrays and unset variables are the same).

As a result I'm forced to use "${@:-}" or something like that everywhere I use "$@" (which is really everywhere). Is there any other way around this? Any way to get a more selective nounset? Thanks in advance.
