Update parameters of ObservedResults?

I came across this discussion stating that it’s not possible to have a dynamic filter in ObservedResult property wrapper. It suggests to filter in the view body instead.

But I was able to update the filter of the ObservedResult like this:

struct SomeView: View {
    @ObservedResults(SomeType.self, configuration: config) var objects
    func setFilter(_ filter: NSPredicate) {
        _objects.filter = filter
    var body: some View { ... }

After reading the code it seems that ObservedResults was designed to make it possible to update the parameters, so I don’t see why this wouldn’t be the correct solution? Did I miss something?
