As is posted on the mailing list at time of disclosure, I’ve been looking for someone among other lightning devs run and play the “defensive” side in replacement cycling attacks, in a traditional “blue / red” fashion. No one has raised the hand.

You’re still free to publish your mainet lightning node pubkey and give me your private consent for demonstration / experimentation. Beyond, I did test replacement cycling attacks locally and it was working well.

We did test some lightning attacks in the past in a real-world setup, though I think you’re missing point than you have so much known attacks affecting lightning that senior protocol devs don’t have time to test, experiment, research and fix them anymore. And as such, jeopardizing their end-users bitcoin financial interests.
