I see where you're going with this (and with the church example) and I
agree up as far as you've taken it. The difference IMHO is that these
are two cases where you would draw a polygon if only you knew the
correct extent. Whereas I'm not convinced that you would want to give
each separate shop in a mall its own private landuse=retail area. I
would instead apply a single landuse=retail polygon around the entire
mall complex (including access roads and parking) and tag individual
buildings as shops and buildings. The shops, of course, _can_
(according to Map Features facism) be validly represented as nodes.
