node/9918746861/history this name ("Park" on leisure=park) is wrong and can be removed, right?

mtb:scale=1-.
was used here, see way/1391245584/history

Maybe
mtb:scale=1-
was intended here?

I am pretty sure that it is a typo, but not sure enough to just replace it (I edited some objects where situation seemed more clear to me).

Or maybe this value was used deliberately? In such case, what was the intended meaning?

If you know it is a mistake - can you fix it?

way/577401051/history is tagged as building = proposed

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.

NSI claims that it is shop=chemist rather shop=cosmetics (which results in suggestion show in osm.org editor)

Is it a good suggestion that should be followed?

Or maybe https://github.com/osmlab/name-suggestion-index should be changed to allow both shop tags?
