Criteria For Getting In Special Extension Discovery Categories

On the extension discovery page, there are some categories that are obvious such as Viewer Engagement, Loyalty and Recognition, etc that you can get into by simply identifying your extension as being in that category. There are several others, such as Trending This Week, New And Noteworthy, and (most importantly) Featured Extensions that seem to have some hidden criteria as to how you can get your extension included as part of that category.

Does anyone have an idea as to what the criteria is for each of these special categories? One could presume some of the the criteria by the category names, but without actually getting in the categories it is difficult to know for sure.

I believe they are manually curated or auto generated based on install spikes.

But it’s not documented anywhere
