In the absence of any supported tag for the purpose it does its job. If 
you saw that you'd know the intention, surely? If the self intersection 
is bothering you, it could be done as two ways:

         2
         22
         2 2
  1111111+  2
         2 2
         22
         2
but the self intersection on something that is not real-world anyway 
hardly matters.

But as I said, I'd much rather have a specific, rendered, "more to do 
here" tag for stubs that is removed when the way is extended.
