Difference between "supported" apps, "core" apps, "featured" apps and "official" apps?

A list of “supported apps” is available here:

Also, many different Nextcloud apps are shown here:
Some of those are listed as “featured” apps.

I have also seen discussions referring to “core apps” and “official apps”.

My question is, how are these different kinds of apps related to each other?
Is a “supported” app the same thing as a “core” app or an “official” app?
Is a “supported” app necessarily also “featured”, or are those labels not related at all?

good question @eliasr did you had any answer on this?
