I'd like to suggest it shouldn't matter.

Reading 5546 I find the use of STATUS odd. From the receivers 
perspective it's always CANCELLED so not sending STATUS when removing 
the attendee doesn't make a whole lot of sense. I'd hope the 
client/server receiving a CANCEL message would just set STATUS:CANCELLED 
so the use can see the result. Sending a CANCEL or setting the STATUS 
should have the same effect.
