> what’s the failure mode?

The tool misrepresents what is in AWS, and you make a decision based on the bad info.

FWIW I agree with you it doesn’t seem that bad, but this is what came to mind when I read GPs comment

Fair. Best use might be to double check on the proper UI before making any big decisions, and just use it as a general monitor

I mean sure… but to me that is as likely as the official ui misrepresenting the info.
