One reason I could see not sending a blanket uninstall command would be that you do not want the uninstall to occur if the Java 8 install has not yet happened. The mass uninstall command does not have any way to determine if that is the case and you may not want to wait for Java 8 to have 100% deployment before removing the previous version. It also requires patch manager to have more network access and permissions over the client. I have many machines that patch manager can not issue commands to but do get their updates from it. I can understand separating the removal package from the install and having it's own package with prerequisite rules to detect both Java 7 and Java 8 for the sake of flexibility. I agree that you should use the right tool for the job and in some environments that is a well crafted custom package.
