I have literally never heard a developer utter the words "so how does the customer like the software?"
I'm not surprised, given how many lousy places to work there are out there. But there are plenty of shops where this isn't the case. And where developers do in fact care what the customer thinks, because this obviously (if only slightly indirectly) correlates with the organization's chances for long-term success and revenue, and all that stuff.
None of which has anything to do with Agile of course (because the same issues existed and were dealt with thousands of years before the AM descended to earth, accompanied by angles).
But just saying - yes, actually giving a shit about what the customer thing is a thing, and always has been a thing (at better shops at least).
