Why doen't Sketchfab sell NFTs?

Sketchfab has amazing tech when it comes to viewing 3D content online. Far ahead of anyone else, people are using pre-rendered videos to show off 3D content, and are making a lot of money doing it.

Sketchfab could blow them all away if there was an option to sell 3D art as NFTs, and could probably make a lot of money doing it; it feels like a missed opportunity. Is anyone working on this?

Here is an example of what is passing for a 3D art piece right now, https://crypto.com/nft/drops-event/b539eb3f0483f5d34a265022d8036c4c?asset=3d93ba9fee28ea4ea6eff18a7b2dba64&edition=1a422f694124d52cedf4d39fc5e1ed14
