improved list in method hasAreaTags(). Probably many more candidates could be added.

Based on what StreetComplete lists, I would add:

man_made ~ beacon|bridge|campanile|dolphin|lighthouse|obelisk|observatory|tower|bunker_silo|chimney|gasometer|kiln|mineshaft|petroleum_well
man_made ~ silo|storage_tank|watermill|windmill|works|communications_tower|monitoring_station|street_cabinet|pumping_station
man_made ~ reservoir_covered|wastewater_plant|water_tank|water_tower|water_well|water_works
waterway ~ boatyard|dam|dock|fuel (waterway=riverbank is listed already)
cemetery ~ sector|grave
craft
office
public_transport
place
tourism
military and military != trench
emergency and emergency != yes and emergency != no

In addition, what it be possible to put tags (at least in the initial list) in the alphabetic order? It would make comparisons much easier. (And yes, listing natural entries in both JOSM and SC in the alphabetic order would be likely helpful)

BTW, I created ​https://wiki.openstreetmap.org/wiki/Area#Tags_implying_area_status

It may be useful to track down what other editors/software considers as implying an area and synchronize them.
