TechNet....

I'd like to put in my $.02 for DFT......

We specify 100% netlist coverage for ICT unless there is a compelling design
reason why a net can not be accessed.  It's part of our Mfg DFT requirements.

The rationale.....our boards are expensive and complex.  Having to scrap
out or spend
a lot of debug time at Functional costs a lot more in time and resources
then adding
some test points or taking up a little more real estate or adding a
layer.  I think if you
look at the cost implication of production and service/customers it works
out to a
much bigger advantage to have ICT at the highest level possible.
