Sure.
If an app changes CONFIG_INSTALL_DIR then KConfig (on e.g. an app-global config file) won't work,
if it changes DATA_INSTALL_DIR then locate("data","...") or locate ("appdata","...") won't work,
if it changes MIME_INSTALL_DIR or SERVICES_INSTALL_DIR then ksycoca won't contain its mimetypes/services, making them useless,
etc, you get the point.
It's only possible to change the subdirs used inside a kde prefix if KStandardDirs knows about it...

Sure, choosing a custom prefix is fine. But the organization inside the prefix is fixed.
