What we have just seen is a player admit, on an open forum, that they would
rather spend large piles of gold then have to use a simple command-alias.
I realize I don't speak for every wiz, but I, for one, will not build such a
door. Instead, I would personally code a thief skill that lets them "fake out"
such a door, if one is ever made.
I assure you, the time and effort it takes you to write a command-alias or (if
necessary) a trigger to close your own damn door is a _LOT_ less time and
effort than the amount required to code this magic door.
