I only skimmed the pictures in the article but the ones I saw could have no plausible impact on navigation. They are buried within tiny details that are essentially artistic anyway, there is no impact on accuracy possible.
To allow de minimis excursions from ground truth is a necessary compromise, but purposely introducing them isn't.
Anyone looking to actually do something interesting with a piece of land is going to have to a much higher resolution map of the site, not use the extreme zoom and on a map covering a huge area.
Or they may even go rogue and visit the place! Heavens to Murgatroyd!
(Perhaps sir would like to search 'Ordnance Survey Maps').
