I would go slow on this.
I looked out of curiosity a bit closer, and it looks as if the mappers
involved use a gruadual approach:
they first outline groups of buildings and tag it as a single building or
religious or hospital. At a later stage they (plan to) add details to each
of these groups by adding individual building outlines and footpaths
connecting them to the roads.
One could have done this with a different approach using
landuse=residential|religious|... , but I would not interfere with the
local community's approach without dialogue.
It looks as there is at least one experienced mapper involved in many of
these changesets: Cheibany, <https://www.openstreetmap.org/user/Cheibany>
He has a background in urban planning according to his OSM user page. I
would be surprised if you could not communicate with him.
