It would be impossible to install different IdP versions at the same time because you'd end up with different lib versions being installed in the same directory and thus on the classpath together.  That is going to be very problematic for people who do IdP hosting.  Second, the unit of management within Java (at least for our webapps) is the WAR, which includes libraries (which presumably would be expected to go in to /usr/lib somewhere) as well as various other files (e.g., images, text files like CSSs, conf files like web.xml).  Those other things really shouldn't go in the /usr/lib directory but do need to be in the same directory structure as the libs in order to be deployed.  In short, the Java environment makes assumption that are different than the ones the Linux environment makes.
