+1, agree
I would just add
- flagstone: flat stone slab (taginfo 3 uses)

+1, agree
I dislike this "colloquial", "cobblestone is superset" idea.
I prefer cobblestone as "unworked rounded stone", sett as "worked, cut stone"

I think this cobblestone:flattened can be a good value (not with the
current definition in the wiki, but with intented usage by mappers).
It would apply to old streets where real cobblestone is in place, the
big rounded sort, for a very uneven surface.
On this rounded stones, only the top would be now cut: the stone is
flattened only on one face, possibly years after is was laid. Of
course the surface is more even, but the look of the rounded stones is
not completely lost.
Maybe cobblestone:flattened could be converted to surface=cobblestone
+ cobblestone=flattened.
Maybe some wiki readers were confused and applied many
"cobblestone:flattened" in stead of "sett" but that should be verified
case-by-case.
