This is interesting question.

1.  There is a certain grace to the simplicity of a reference with no 
indication of what to do with something.
- Such a reference is much more reusable (you can bookmark it, email it 
etc);
- It corresponds to a "place" in the "navigation" of the hypertext, so 
human beings can use their inherent mental navigation metaphors;
- It respects that the user may want control of what to with the thing.

Yes, sometimes the author wants to suggest that a new window should be 
opened. We start to slip down a slippery accessibility slope and device 
independence cliff if not careful,  but it is useful to specify a 
target window for example.  Of course if you take this to extremes you 
end up with scripting languages, and questions of how to make the user 
aware of what he or she is actually doing.  You are wright that if you 
are going to specify a more complex behavior then it is logically part 
of the link.
