Hi all:
I was the one who organized the import of 14,000+ places nodes in
Liberia back in September 2014.
The idea of giving place=unknown (together with a fixme=* tag) to places
that were not possible to determine its value was proposed during the
discussion in the imports list [1] [2].
place=yes was also proposed, and now I guess it would be better than
place=unknown
Back in 2014 many areas of Liberia lacked hires imagery. Now we have
imagery for all the country.
2 days ago, the number of nodes with place=unknown was 977 (so 7% of all
the imported nodes). In a short time I retagged more than 100 (they are
861 nodes with place=unknown left (6%)), a quite easy task.
So I strongly oppose to the removal of these nodes, that could be
retagged quite easily in a short time.
As for the nodes that cannot be retagged, we could change them to place=yes.
Cheers,
Rafael.

I recently seen a variety of keys being given the value of 'unknown'.
I'm struggling to see its purpose. It confirms nothing & adds no value to
the database. Am I missing something?
You are right.
It's interesting if you take a look at some values.
maxspeed=unknown basically happens only in the Netherlands, from the
same author (it seems) who is mapping/importing railway data.
owner=UNKNOWN in California, USA, from an old buildings import
place=unknown in Africa (due to this import
https://wiki.openstreetmap.org/wiki/Import_Liberia_UNMIL_Places#Tagging_Plans)
bench=unknown are mostly in Italy (from some possible bus stops/routes import)
foot=unknown in England
naptan:Landmark=Unknown also in England (both foot and naptan:Landmark
look that are old data)
wheelchair=unknown mostly in Iraq and Saudi Arabia (also from older imports)
By taking a quick look at them, most seem to be from imports, created
by the same mappers or old data.
