it is a long standing definition in the wiki (almost from the beginning of
the building tag) and it is still there:
"Buildings can simply be building=yes or use a value that describes the
building typology, for example building=house, building=hut,
building=garage, building=school. See building=* for a more complete list
of options and have a look at what is actually used. "

it is clear that in a project like OSM and with a key that is used millions
of times, there will also be some outliners, but I don't think the best way
is to encourage ignoring the standing definition. If you need a key for the
function in a building (i.e. the current purpose), invent a different tag
(although usually you already have this covered with amenity, man_made
etc.).
