As someone who was the first person to use this tag largely in Mumbai, i support the removal of the tag as well and am happy to do it if theres no other objection.

Just to explain why i was using it in the first place, around 10 years ago i was filling in large unmapped voids in Mumbai and was using this tag to distinguish areas that needed to be mapped in significantly more detail since aerial imagery wasnt clear. I can understand why the tag might sound offensive, but it was used merely to describe structure typology and even fishing villages which are not slums had predominantly shanty structures and i used the tag there.

Without any tag documentation though it serves little purpose to anyone, so is better removed. Thank you Heinz for bringing this up.
