Why not support it with --single-version-externally-managed?

No, but it's a subclass of the install command. It's caught by this  
in setuptools.command.install.install.run:

         caller = sys._getframe(2)
         caller_module = caller.f_globals.get('__name__','')
         caller_name = caller.f_code.co_name

         if caller_module != 'distutils.dist' or caller_name! 
             # We weren't called from the command line or setup(), so we
             # should run in backward-compatibility mode to support  
             # commands.
