Hello emilmaks, 

I have reverted your deletions. On OSM it is perfectly acceptable to map features others might deem as not critical or necessary. As long as the object actually exists, it can be mapped. 

Deleting objects that you do not wish to see on the map, whether you believe it to be a burden, clutter, unnecessary, or optional, is not a valid reason.

Best regards,
