[Sidetracked by my anecdotes...  :< ]

Anyway, the question posed is how to address the "product as delivered"
(in terms of hardware) requirement inherent (and mandated) in validation
for those markets where there are no "rules".

How much can you alter the hardware and still, in good conscience
(and, more practically, in having faith in your results), attest
to the fact that you have verified the product is what it SHOULD
be, despite any deficiencies in the specification(s)?  When are
you rationalizing equivalence just because a true "as delivered"
environment is not possible?

[How do you test subsystems, on which you rely, inside an MCU
without a bond-out option?  Or, do you simply say that anything
that can't be tested need NOT be tested -- and not even make
an attempt to do so?  E.g., Why do we checksum internal FLASH?
Can you simulate a failure -- without altering the hardware -- to
be able to verify that you can detect it?]
