Honestly, schools like this kind of assessment because it feels like it has good face validity to teachers. The points are derived from tasks and observations that are familiar to teachers. Plus, let's be real, Dr. Kingore has a pretty good seat on the author/lecturer circuit.
Back when I was on the gifted program selection committee, the GT teachers loved their teacher-created equivalent of the Planned Experience, yet it pretty regularly screened out some of the top scoring students on the CogAT (granted, with all of the limitations that instrument has; but at least it's objective).
