I'm afraid that you are way over their heads...
This year will show if WGT will include the upcoming venue, Country Club in Brookline, Mass
From that we may guess what 2023 (L.A. CC) and 2024 (Valhalla) may bring.
BTW: It's of no importance that Valhalla is already available as a CTTH course. It was published 10+(?) years ago, with no follow-up.
