> I also wonder how long the increase in quality in Havelhöhe can last before some beancounter sweeps in and turns the system on its head again based on some pretext. I hope that this never happens, but reality has a way of throwing a wrench into the works every time.

I would not expect much bean counting here besides scientific studies and their results:

The hospital is part of Charite[1] and as such has the status of a research/university hospital and an anthroposophic[2] orientation in which food arguably plays a role beyond what is scientifically proven.

I also have to say that I did spend quite some time in German hospitals and my rule of thumb: The bigger the hospital, the better the food. Never was it as a bad as the regular in-flight meals in cattle class.
