Please keep in mind that there are not only shelters in the countryside
and the mountains but also at thousands of bus stops. While shelters for
hiking usually look like small buildings, shelters at bus stops don't.

The following three are no buildings from my point of view because they
have one wall only. Either the two other walls do not fully stretch from
the ground to the roof or the shelter itself can be removed easily.

There is building=roof but I would not use it for such shelters. They
are not treated as buildings by the cadastre, why should I do? (If they
are larger and have no walls, they

I think that nobody of us knows the whole world and that's why I ask you
not to decide on the default values of the whole world. If local mappers
think that a shelter is a building, they will tag it as such. If they
think that it does not qualify to be a building, they will not add the tag.

Adding missing default tags is easier for data consumers than removing
potentially wrong and superfluous default tags.
