Jerry,
I would like to use the qip file to make it easy to integrate various reusable modules. In my environment, each module is in its own folder. There could be more than one file for each module. e.g. sub-modules, sdc files, etc. As the modules are reusable their folders get copied around. And adding each file to the Quartus QSF is a hassle. QIP makes it easy as it is just one file.
A script to create the QIP file makes it even easier.
