Custom tile features - possible for regular tiles?

With interest I’ve read about this blog-post:

And I have already replaced many of my entity cards with the new tile card.
Especially, when the entity has the type “button” or “switch” - I would love to see a button / toggle-switch as feature on those cards.

Is there any way to get such a feature in the future or maybe with using the new “custom-tile-features” somehow?
