You might consider it analogous to streets: at first they were mostly traced
from aerial photos, and then mappers visited on the ground to fill in names
(and other things as a side effect).  This is certainly what I've been doing
for the past couple of years.

So yes, it would be great to trace the buildings from the OS maps (which
would be just as accurate as tracing them from low-res aerial photos) and
get them into OSM, even if the address is missing.  If the NoNames map then
highlighted buildings missing address info, that would motivate people to get
out and add the addresses.

(FWIW, I think just building shapes without any addresses are still useful,
especially on council estates and other areas that lack clearly defined streets.)
