It still makes sense for small lt 1TB systems, IMO.  But ... maybe a
flag of some sort is necessary to stop the TAINTing for systems larger
than that.  The CEs may point to something going wrong on a system.  CEs
in theory become UCEs eventually, right?

/me knows this is going to turn into a PFA discussion in 4 ... 3 ... 2
