Relay of full-rbf transactions works well right now precisely because a few
implementations exist of preferential rbf peering. I'm personally running four
nodes with it enabled, two using my own custom patches, and another two using
ariad's patch:

I haven't seen a lot of non-opt-in doublespends get mined. But I have seen a
few now via my Alice OTS calendar. This can of course increase dramatically as
miners turn on full-rbf.
