Might well be that this becomes a lot more common on cheaper phones if it becomes a popular feature though. A display port output isn't currently that useful, so it's something it makes sense to cut from budget models. But if this desktop functionality becomes popular that calculus may change.
I am pretty sure brands would rather sell you additionnal devices, like tablets or chromebook (will they be called androidbooks?) than make budget models able to do so.
