What are the pros and cons of whether or not to default all Packages to Units in Rhapsody Model Manager?  I have a team of a few dozen modelers working on a complex system model. We are currently configuration controlling our model in SVN, so we have turned off the setting to make every package a unit (in order to reduce the amount of CM operations we have to do in SVN). But we are going to be moving to Rhapsody Model Manager in a few weeks. And I am wondering if I should manually go into the model and make every package a unit after we convert to RMM, and change the project property to make every package a unit going forward.
