Hi Claire, Hi Imre,
Thanks for your responses.

I searched for OSMSharp and found only a low-level C# implementation
for OSM. Where can I check how this works coupled to HOTOSM tasking
manager? Would this work on smartphones? Because at the end of the
day, the POIs need to be verified on the ground. In the best case,
this would be as simple as on StreetComplete.
Thanks Imre for the thorough analysis.

Yes it might absolutely make sense to map those.

Most of those tags can probably be cleared. But there are actually
houses with the number sign "New", when a house number was not yet
assigned.

probably this should be converted to a disused:shop:kiosk tag and
would also need manual verification.

We can safely remove such tags ...

Probably this needs lots of manual work, as due to the transliteration
there are often different spellings. Wondering if there are scripts
which use a fuzzy search for identifying such cases and make the
manual duplicate check more efficient.
