I'm personally not torn on this; for me the whole point of
implementing this functionality is to add resiliency to the existing
DNS ecosystem.  Very specifically for my implementation it was needed
in an environment where answers were going to a stub resolver that did
not (and still does not) speak EDNS.

It is significantly less operationally beneficial if it demands EDNS.
