I agree as wel, for the record :).

I don't think you have to, as I don't think there is any point in using 
this method from these methods - and if you really think otherwise, we 
could still emulate the single message approach, as Stephan proposed.
I don't think it's used that often anyway in any function that deals 
with BView messages.
