It just seems really odd that the acceptability of a runtime link would be dependent on the name of the folder.

No, it's logical to do that. Nearly all Poser content has relative references starting with ":runtime:" and Poser will have a hard time finding the right file if you don't have a "runtime" folder, because all references are wrong then...
