I am not entirely sure. Is the difference between: (1) a number of reusable modules/components (I am thinking of, say, maven artifacts in a private repository, something along a private CPAN) and (2) the evil Uber-Application that: in (1) you take several modules out of the sea of modules you have and integrate them into the software you create for the customers needs (potentially adapting or refining the modules) while in (2) you rather try to bend a single application and the customers will in a way such that they eventually meet somewhere, forming some sort of application which sort of meets the customers requirements? If this is the case, then I think I agree.
