Personally I’ve always just hung my food and never had an issue on both south fork and Vivian Creek. Only heard of the Forest Falls residents ever having an issue with bears. But if you’re willing to sacrifice the weight it will never hurt to bring the bear can along.
Fun fact though, our bears are all descendants of problem bears that were brought down to SBNF from areas like Tahoe and Yosemite, so likely hood is they are extremely intelligent as bear standards go. As the populations grows I can see there being issues sooner or later.
