shop=machinery ? What kind of machines? Industrial machines? Washing machines? Computers? (see osm.wiki/Key:shop for possible values - though maybe new one is needed). Or is it not actually a place where you can walk in and buy stuff? But rather internal company office tagged as office=company?

Hello! osm.org/node/11756655230/history has shop = metaphysical that was added in this edit
shop=metaphysical ? What kind of shop, if any is here? Is it intentionally used instead of osm.wiki/Tag:shop=esoteric or osm.wiki/Tag:shop=new_age ? If yes, what is the difference?

Should we document this shop value as distinct, valid and useful? Or maybe it is so obvious duplicate that I should have replaced it with an automatic edit rather than making a note?

Hello! osm.org/way/916588240/history has surface = tarmac that was added in this edit
is it an actual tarmacadan? In such case surface=tarmacadan may be a better less confused term (tarmac is widely used for asphalt and concrete surfaces)

Or is it just a regular asphalt surface? Then surface=asphalt would be better

see osm.wiki/Tag:surface=tarmac for some documentation

Hello! osm.org/way/1341501813/history has building = proposed that was added in this edit
Is this building existing now? Are there at least real plans for building it? If there are no serious plans for it - that should be entirely deleted. If construction started then building=construction is a better tag. If construction is upcoming then source for this claim should be tagged on the geometry itself (source tag, note tag) and different tagging should be used - we are mapping proposed features in OpenStreetMap very sparingly, not every promise or business plan should be mapped here.
