Sure it is. Sometimes all a client needs is ammunition to take to the boss
to show them that they security budget they have been clamoring for is
really necessaray. What is and isn't "useful" is highly subjective in this
sense. Not to mention that the end utility of your service is for your
client to decide.

That's not a pen-test, that's a full on audit. 2 different beasts. Yes, an
audit is often significantly more useful, but it is not always appropriate.

goes to your credibility, why would you do any less?

what you'd like to see and what clients are willing to pay for may be 2
different things.
