If there is not enough mappers then likely mapping more building as building=yes
is more efficient than using specific building value anyway.

And anyone may map whatever (s)he wants, it is perfectly fine to 
map roads without mapping buildings, map trees instead of mapping roads,
map buildings as building=yes, map bicycle parkings and map no shops at all...

Note also that for example StreetComplete allows newbies and beginners to
build on build on initial not finished data and for example specify 
more exact building types.

No. TIGER import had plenty of outright invalid, incorrect and insane data.
This is merely missing not very important part of info.
