The lack of consistent proxy loop detection across implementations will make
this messy.  If downstream router will consider route R a loop, but upstream
sent it, you now have a discrepancy that will show up in a mechanism like
this.

What do you want the behavior to be?

Add-paths means that you'll send R1, R2, R3 all with the same destination.
Are you really happy getting back R1, R2, R3 with the same path id as
confirmation that the route is eligible?
