Let me try work on it.

As I understood issue is then f3d is installed, GUI part of OS should be able to generate thumbnail for it based on f3d support for this type of file?

I never worked with thumbnails for files before, will need to learn what is even a mechanism used for it

Lets sync on discord when you can.
