I have never taken advantage of this, personally. Given that there isn’t anything that this feature enables that can’t be done if it’s removed—aside from reordering arguments—I’d be in favor of removing it for simplicity’s sake.

This special case adds complexity to the language, and runs against our general trend of treating argument labels as a significant part of an API's name, and preferring a single way of writing API calls. I think it's worth revisiting this design choice—is the special case worth the complexity? How many people take advantage of default argument reordering?
