It kind of gives both sides what they want:
The mainstream guys can say the simplifying assumptions are pretty reasonable (and they aren't crazy), so really all the Austrian insights have been incorporated already,
Meanwhile, the Austrians can say the simplifying assumptions don't allow for all realistic conditions (they don't), so mainstream analysis can't be trusted.

Undisciplined

This does seem to be a weird sort of double think that economics is stuck in

"While most economists admit that value is subjective, they still err by concentrating on scarcity and choice instead of purposeful action by individuals."

Going through a mainstream PhD program is interesting for those in the Austrian School, because most of the Austrian insights are at least given lip service. Then a bunch of simplifying assumptions are introduced that let mainstream economists get on the kind of mathematical footing they're comfortable with.
