I've gone through this same mental exercise. I don't think at the time linux extended attributes were as mature, or I wasn't aware of them.
But what if I want my files on a thumb-drive - with no attributes. Or on Amazon photos (where they don't even export correct file dates!) And are Linux attributes compatible with Windows attributes?
So, for the moment. I'm using #Digikam which is mult-platform. It does mean that you can only move files with the same tool, but ...
1/2 (maybe)
