One place this causes a minor display problem in the MagicDraw/Cameo tool is in Element Properties for 'allocateTo' and 'allocatedFrom' in compartments and in callouts to Notes when usage level allocation from CallBehaviorActions to part properties of a Block is being used, in which case it may not be clear which elements are involved in the allocation.
For the sake of comparison, the Element Compartments are using SysML Callout Style and the Note callout is not.
In practice, it's not a big issue, and certainly not sufficient to overrule the benefits of using anonymous actions and anonymous properties (where practical). You can use the context menu items to navigate in the tool. And in any case, Allocate tables and matrices offer a better bigger picture view anyway.
