I agree with you, and that's how most of the time I was doing my API replies. I was mostly curious on why people are doing it differently.
One explanation on why it's better to have an array of objects is that it's easier to map the response in strong typed languages like java or c#.
I guess. I've never used JSONApi so I can't comment on that either. I'm definitely, sadly, in the RESTish camp.
Technically JSON API is rest, let's say just a bit more structured.
