As far as the physics code goes, we will make the physics code work the way the public opinion pushes it. I was in favor of fixing the "bug" that causes the inprecision in the code but if it changes things that much then we need to put it back the way it was. We can essentially allow the physics code to behave the way it did (in both DLL's and vm's) and correct the problem elsewhere in the code that needs the better precision.
Splash damage through floors was a bug. It is fixed, live with it.
