This is just speculation, but I suppose it's because Apple is also collaborating/contributing in the EU Chat Control 2.0 legislation, so they may have some argument that completely opening the door for uncontrolled app installs may not allow them to comply with such legislation.
replyAs I said, just speculation, but this is how most of the time these things go
While the app store was a much better deal than ISP stores for the smartphones when it was introduced, Apple's hubris is too much and, almost no app developers care about VisionPro exactly because of that, it isn't only the price.
replyThe extreme discomfort of eye tracking based interactions for power users is what kept it off of my head. You have to maintain eye contact with the ui element you want to touch throughout the entire gesture. It’s kind of miserable for someone who is fluent with computers.

replyAh, I think it probably is the price, though Apple's hubris may be the cause of them thinking a product at that price was ever a good idea.
If you're a developer, chase the users. AVP is extremely expensive, so there's not a lot of users, so not much reason for developers to care: even cheap VR hardware has problems getting enough users to justify the effort to make games (let alone other apps) work well on it. Even ignoring AVP, the whole category's sales are, what, mostly Beat Sabre? I think? You don't need a 3.5k device for a rhythm action game.
