Feel like a mistake that Apple makes dev opt in/out to iPad app support, same issue on M-series Macs there are iPad app that just don't show up in the app store on Mac because the dev didn't check the box to allow it. They could perhaps warn that the app isn't tested for the device but otherwise allow all iPad apps on Vision Pro and Mac's.
