But is every feature in a browser supposed to be standardized? Like, it's against the rules somehow to develop features without asking permission from Apple and Mozilla?

It's not against the rules, but it is hostile to the web. Forking the web because a company is big enough to do so may sound just dandy to you, but to the rest of us who have spent decades working on interoperability it's a big middle finger.

Allowing Apple to have a veto on which features are allowed to be added to a browser is even more hostile to the web.
