They hate to admit it, and it’s definitely less in-your-face most of the time because of the expected formality of the scientific community, but physicists, and specifically those trying to make advancements like we see around black holes, are SUPER arrogant. For the first 2 scenarios listed, they usually only make a formal paper out of the discovery to later defend the drawback as something they can “work around”. Either by “oh we’ll definitely eventually figure out how to emperically verify this haha. Look how well it works, you’d be crazy not to believe in this”, or the more extreme “This obviously constitutes a whole rewrite of our understanding of physics because my solution is so elegant except for the parts where it literally doesn’t work”
That last one is less prone to arrogance because topology is working with an insane amount of unverifiable possibilities already, so they don’t really tend to get too attached to any given solution.
