It's only misleading if you don't understand how to use it. I put the runway threshold in the PROG page as a standard setup, but once flying the arrival I might use the FPL distance remaining, the DME, or put another more relevant waypoint in the PROG page. If I'm downwind at 10 NM to the RWY then I probably don't want to be any higher than 4000' if I'm expecting a base turn soon or I could be higher if I can see that aircraft ahead are being turned at about 15 NM. And to be quite honest, I almost never look at the distance on the PROG page again as I prefer to use the DME. If I'm using the PROG page I've probably entered a more relevant waypoint.
In short, the distance to the runway is a data point to be used appropriately, you shouldn't just be blindly following it.
