The main reason is to have one event less in the stream API (if we will keep 
the current alias mechanism, I will have to create an add-alias stream 
event). IWBN to keep that API minimal, and to me it seems that aliases aren't 
much used anyways.

However, you have a very point that functions like \applyoutput will get more 
complicated if we want to keep full backward compatibility.
