The definition in 2445bis is (and I don't think this changed from 2445 
either):

This parameter can be specified on properties with a
      CAL-ADDRESS value type.  The parameter identifies the expectation
      of a reply from the calendar user specified by the property value.
      This parameter is used by the "Organizer" to request a
      participation status reply from an "Attendee" of a group scheduled
      event or to-do.  If not specified on a property that allows this
      parameter, the default value is FALSE.

That implies to me that an Organizer really SHOULD (or even MUST) set 
RSVP=TRUE if a reply is expected back. Plus an Attendee SHOULD send back a 
reply when they get RSVP=TRUE.
