Okay, but my question is what was achieved by including them on the map, not what is their official status and function. Official status and function aren't really relevant to someone trying to figure out how to get somewhere. This isn't a status or function map, but a wayfinding map. Those clusters are not close by, and none of them really amount to anything (there are not really comparable in any way to the Berri-UQAM cluster in Montreal which connects the UQAM campus, the Grande Bibliothèque and the bus station, and is among the most used portions of the underground). If the map can be made larger and simpler, and thus more user-friendly by deleting clusters that are not connected to the main PATH, then frankly I don't see what is achieved by including them on the map. If those other clusters aren't particularly relevant to users trying to get from A to B in the main network, then eliminate the irrelevant information. Finding one's way in the PATH is hard enough if the map is cluttered with extraneous information for the sake of status and function.
