This is the way it's designed.

The alternative is to do what we currently do for physical replication,
namely requiring the user to set up all the replication slots manually
beforehand.  I don't think that's a better experience.  There was a
thread about having pg_basebackup automatically create replication
slots.  That will have to deal with the same issues.
