armchair mappers without local knowledge are not the preferred source anyway, but foo=unknown is a really bad idea that should not become standard. 

Otherwise a lot more tags can be added with very few benefit:
maxheight =unknown
maxspeed, maxwidth, snowmobile, horse, foot, bicycle, hgv, hazmat, surface, name, ref, lanes, start_date, width, operator, cycleway, bus, psv, etc =unknown

We could also add turn_restrictions with unknown restrictions, e.g.
from to via etc.

Or we could draw unknown objects under the ice shelves of greenland, the antarctica or in other permafrost regions.
