Uninstall App-v package create 2 collections but also 2 applications?

Hi,

When designing an install/uninstall App-v strategy on SCCM, we used this: http://blogs.technet.com/b/configmgrdogs/archive/2014/11/03/managing-app-v-deployments-in-configmgr-2012.aspx what works fine = 2 collections uninstall/install.

However, the question now is if adding an extra application (1 for install, 1 for uninstall) would give extra flexibility/is needed or just overhead (f.e. install 7-Zip with App-v client dependency, when you deploy this to uninstall collection, it would INSTALL Z-Zip since it is a prereq, right)?

Please advise.
