There are many cases where the content we want to place inside a Component Slot cannot be turned into a component. It would be preferable if any content can be placed in this slot, and not just components.

One example from my project is on a Collection Page for Case Studies I have a CMS Collection List Photo Gallery that I want to place inside of my "Box" Component, which is just a styled wrapper of content. I would use a Slot, but can't because the Collection List is linked to a property specific to that page, therefore I have to unlink my Component which definitely defeats the purpose of a Slot in the first place.

There's a lot of potential for Component Slots, and adding this would make them even more powerful!
