Nice. I dont know if you have access to it. but if you have the time and willingness you can put the actual locations (positions) into the Documentation/Wiki under 'World ID's Spawn locations' (like some of them have it at the end: //new FVector(x,y,z)).
EDIT:
Note that some could be wrong on Slinks testserver as there they are most likey set by hand (or he found a way to parse the files :-P). But for those if you happen to know the real ones, go there, type .loc and collect the positions
