Sure, would be an option as well, but it is not as user friendly as 
uniqueInPid and it does not prevent a user to set two pages to the same 
nav_title (uniqueInPid takes care of this, too). The basic problem is 
that the nav_title is not shown in the page tree, so the FE link name is 
a bit "hidden" in the page properties. Thus, a misconfiguration can not 
be seen directly.
