@HellMap (and @tux67 & Carnildo)
So, by your own admission Your argument is straw man. *All* of the errors were in existence prior to these edits. These edits created no errors. The only reason you've become aware of these errors & thnk MapComplete is a solution to fixing them is due to edits occurring. Discussing them before hand wouldn't have enlightened you. If there are errors, fix them; instead of moaning about other edits which improve the quality of the OSM database.   

@ZeLonewolf
As the edits haven't created errors, only tidied up deprecated tags that have already been discussed at length, what's your logic for "getting mad"? Communities should assess on quality, not quantity.
