Well arguably one may call the Austrian School even more debunked but there is two problems with that:
1) austerity was pretty much just a diet version of Austrian school to begin with so it's really the same thing
and 
2) Austrian school has been deemed heterodox (an academic euphemism for bovine-excrement) for many decades already, but it's own adherents don't admit it's debunked because they reject the scientific method. So they aren't so much economic science as they are economic homeopathy - only they work even less well than homeopathy since the economy tends not respond well to placebos.
