I think everyone was shocked because he left with no warning or explanation, and the fear was that he had defected.
That doesn't preclude the possibility of Spock being sent on an official ambassadorial mission to Romulus before Kirk dies
on the Enterprise-B in Generations.
Anyway, this was a Spock centred movie, and having Shatner in at the end, or doing the voice over when he had no other role in the movie would have been way too corny.
