This is assuming there is a robust set of "other 'loss source'" available. This is far from reality for the vast majority of cases.

Also, the loss bits(s) would allow one to determine whether the loss is upstream or downstream.  That would allow you to know "whom do you call".  I.e. is the loss in your transit or peer? Is it in the user's own home WiFi network?  Or is it really in your network?

In general, it is important to keep in mind that we live in the world as it "is" and not in a world as it "should be".  I know little of ISP tech support business, but if ISPs says they have no other tools, I believe that they have no other tools currently. We can to encourage change, but if you push too hard, the reality has a way of pushing back.
