The exact term can be discussed, that's why we need a proposal. I think 
there are good reasons to keep track of demolished features. One is for 
recording the past (think a "openhistorymap.org"), another reason is to 
prevent accidential remapping of features that have recently been 
demolished but are still visible in aerial imagery. The undergrounding 
of power lines is a good example.
