and things get more complicated with exceptions, e.g. motorway_links are assumed to be oneway (as are motorways), so there are some cases where oneway=no is “required”. 
Or recently I had a discussion about overtaking=no being the typical situation on 2 lane roads in the US (it was at least presented like this), while overtaking=yes is the assumed default when the tag is missing.
