They are still there so they remain on the map, what's numbered are the stores or restaurants that remain open. Notice on the map how they changed the artwork for BET to just say sound-stage club... even though many buildings are empty they help for visual references when looking for somewhere else.
Exactly. Even though Wonders of Life is closed, it's still on the Epcot map as a visual guide when you're in the park.
The MK maps still show the chalet that was the Fantasyland Skyway station. And in the new planning DVD, because it was presumed that Space Mountain would be closed off for most of 2009, it's not labeled but it's still on the map.
My fraternity house is a good example of how removing from the maps any buildings that people would use as visual landmarks can cause problems:
On the published maps, the school only shows school-owned buildings. When it was built for us in the 1920's, the fraternity house was located over a block away from the edge of campus. Over the years the school expanded around the house and it's now 2/3 surrounded by school property. But on the maps, the triangle of land and our house is shown as grass and a few trees.
Every semester, without fail, we'd get people visiting the school coming through our front door thinking it was the Admissions building (also a brick building) which is located diagonally across the street from us. When it gets really bad, we'd have to post a sign on the front door and keep it locked.
Guests get lost in the parks often enough as it is. Why make it harder by erasing anything that's still standing in the parks but happens to be closed? (Besides, if they just change the overlaid graphics on the maps, they don't have to pay an artist to re-draw the map...)

EDIT: Though I will say that the "lights" shining out through the doors and windows from inside the closed clubs on the map is a bit too much... (Or is that the artist's representation of worklights from construction crews?) :lookaroun
