You're right that it doesn't add all that much... just thinking aloud... you have to admit, though, if you put yourself into the perspective of a complete newbie, "use this track as a device" and then having a corresponding icon makes a heck of a lot of sense.
The way it is right now, if/when the newbie DOES discover the current functionality, the next logical thing that they ALWAYS seem to attempt to do is record audio coming from the source track, but with the current system, "Track 3" isn't actually being fed into "Track 5", it's actually being fed into the beginning of "Track 5"'s filter section.
