It would probably put an end to the acrimony about ES4 being too  
different from ES3; I'm hesitant to speak for the views of others, but  
I suspect this change would make the language a lot more palatable for  
many currently opposed to it.  In that light, "compelling" is going to  
be a highly subjective measurement.
