Poor Scripting Prevents Unloading From Maps

This has been annoying me for a loooong time. For some reason, scripters think that this is the best way to write a npc that appears in multiple places:
[code]some_particular_city,x,y,d script somenpc viewid,{ ... }
some_other_city,x,y,d duplicate(somenpc) somenpc#1 viewid
yet_another_city,x,y,d duplicate(somenpc) somenpc#2 viewid[/code]
This design requires that the first map must be present at the time of loading.
Otherwise, script loading will skip it and afterwards all duplicates will fail to load too.

Is it [i]that[/i] much of a problem to make a floating mapless npc and clone from that?
