My OFM will mark them as unpaved. The combination of track and grade3 counts more than the surface. I think the current default rules assign them also as unpaved. Your patch v3 too, is that correct?

And what about combinations of surface meaning paved with tracktype?
The wiki says "Usually ... " or "Almost always an unpaved track" for most
tracktype values.
I see quite a lot of ways with
highway=track & surface=concrete:lanes & tracktype=grade3
in my Niedersachsen: http://overpass-turbo.eu/s/lNI
I think those are not unpaved, no matter how nice it is to cycle on them;-)
