ٱلسَّلَامُ عَلَيْكُمْ, 
as-salāmu ʿalaykum,

in addition, i would like to support this edit with the review of the previous mapper's action https://www.openstreetmap.org/changeset/154634809, where the changeset tags are interpreted to be insufficient to be accepted as valid orthophoto tracing. 

Hence ,"mass deletion" flag raised of this changeset 171221344 has effectively been put to rest.
