we have a disused namespace for this sort of thing. it relieves the carto
developers of having to check disused=yes; the data is in the db but
it doesn't mess with the default rendering.

if people want to render disused pubs, the data is there and they can
use it. of course if the pub is torn down then it should move to OHM
if it's of genuine historic significance.
