Unfortunately, many times when designing PCIe or sRIO systems, you only have
control of one end of the link. You can't assume to know the absence or
presence of blocking caps on the other end. As a consequence, you are better
off with double blocking caps than none at all...

And as many of us have learned over the years, specs are guidelines (sometimes
only helpful suggestions) but do not define the known universe of how things
work. There are times when the best solution is to intentionally "violate"
specs with the knowledge of what you're doing and why you are doing it. Gary's
example would be a situation where one might need to knowingly violate specs.
