I think it's important that all games that should be included are, as games see a significant boost to interest from simply being in the bundle, e.g. this person seeing 3000 downloads of their game suddenly: https://twitter.com/king_spooner/status/1271617730467237888
I don't think the 'supporters collection' will see the same interest in their games (as it will be a less viewed list). 600,000 people owning your game with the possibility of taking enough interest to download is quite something for many devs.
