Yeah. I added them because PopOS and Cosmic is super popular, and if they didn't use the money exclusively for that and other open source projects, it would be considered fraud I assume. But, it is an option..
I actually really liked Cosmic, but I have keyboard focus issues with it at the moment. The Windows stacking is awesome, and given enough time, it could become a more serious competitior. It would be a pity to see it dropped.
