This approach would be interesting to reduce the future need for the smoothness tag. To make differences more evident, I believe we could define in the wiki: - pebblestone: loose small rounded natural stones - cobblestone: jointed large rounded natural stones [1] - sett: large natural stones cut to a flat top, usually jointed and forming a regular pattern [2] - paving_stones: smooth tightly-fitting natural stones or artificial blocks, usually forming a regular pattern [3] This would change the wiki in the following ways: - cobblestone: no longer a superset of sett - sett: no longer required to be always regular Then the two cases I've presented recently would become: - portuguese_pavement -> paving_stones: because the gaps are tight and the surface is smooth - "polyhedral pavement" -> sett: because the gaps are somewhat wide and the stones are cut to be flat on the top Then there is cobblestone:flattened, which I think should be discouraged according to the text.
