Is it consensus to use "sett" instead of "cobblestones" for most of the stone pavings of roads? Taginfo shows only 177 objects tagged with "sett".
How should we deal with this? Maybe there was indeed a definition gap to distinguish on a finer granularity between different pavings?
You shouldn't be using "sett" instead of "cobblestones" in any case, because they're not the same thing. My understanding is that cobblestones are irregular stones, used in pretty much their natural state for paving, whereas setts are specifically shaped, brick-sized pieces of rock (granite in the case of Guildford High Street, where I live) that form a smoother surface (but not as smooth as a metalled road).
Paving stones, I'd venture, are another class again, where they can either genuinely be flat stones or cast material, but larger than setts or cobblestones, perhaps over 50cm.
In summary: I believe the three classes to be separate and non-overlapping. So I disagree with the wiki edit made, but do think surface=sett is a sensible, verifiable tag.
