My hope would be that A&A have a process manually whitelisting the route that made the test fail because in fact (as of course it would be) it's actually deliberately not signed but it is really their route.

But on some level that's like assuming the reason the guy with the handgun is on your plane is that he's a sky marshal and not that some idiot let a concealed handgun through security. I mean, sure, maybe, but, maybe not.

Without asking it's just a guess and I haven't asked. Maybe I should.

And now thanks to jsty's sibling comment I don't have to ask, thanks! It does seem like they've been more than "cautious" enough at this point and should just implement RPKI.
