Right, which is not what the average Joe expects.

Nick, these ****'s over here were actually around in 1996 when this was 
added and understand very well the difference between AddType and 
AddHandler.  The folks who understand the difference can of course use 
either, but for those who don't, AddType's behaviour is the one people 
understand.  If we asked people to go and change all their AddTypes to 
AddHandler it could actually cause a number of nasty security problems 
so we have no motivation to do that.
