So people can plan their future journeys for when it reopens, and you
don't have much to do, to update the map, when that happens.

I will include it in the map of future extensions (which is yet to be
released).
The important feature of my map is that it only shows active parts of
the network - so, for example, in weekend disruptions map (like the
one currently available at http://www.fxfp.com/lib/tube/ for May 12
and 13) all "incapacitated" lines are hidden.
