Theoretically yes. In practice one implementation (lets say the market  
leader) will fire the event when the listener is registered and everyone  
will be required to follow. Wishy-washy requirements do not work on the  
web. If you want interoperability implementations will have to do the  
same, pretty much always.

Aside from that, I do not think this group should change the semantics of  
addEventListener(). If you want to change the semantics of  
addEventListener(), please bring it up on www-dom@w3.org.
