I would need to read more to "get smart" here, but I think another 
factor to consider is the number of "true" i686 processers running this 
release vs the number of x86_64 processors running this release under an 
x86_64 kernel.

My understanding from a quick read of the docs here (although, about 2 
minutes worth so i'm very open to being convinced otherwise here) is 
that disabling this would disable CET for sudo:i386 when running under
an amd64 kernel, in order to allow a i586 to run a i686 binary.
