So, if I understand you correctly, you don't really have any specific things that you believe go wrong, it's a diffuse "stuff breaks" reasoning?
I'm not trying to be dismissive, but it isn't a lot to go on.

The wiki has some specific issues it enumerates - OS upgrades, volume permissions, etc. I think the setup I describe, having the OS on completely separate disks/volumes from the shares, etc address many of those concerns. 

I guess I was hoping for something more detailed.
