I think the problem is that the measurement, detection, and access to so-called gifted and talented programs is a major issue. The more exclusive the programs are the more it restricts the access to advanced studies to students not lucky enough to make the cutoff. The differences of students on one side of a cutoff and the other side of a cutoff are negligible. I prefer systems that make advanced coursework and guidance available to anyone willing and able to put in the work. And the "who" may vary from year to year or course to course based on the individual student interest.
