I don't understand why you need that flag at all. Why not simply
take all streams that are on the old default sink and move them
to the new default sink?
It's really weired that streams that are currently not on the default
sink should jump to the new default sink if the default changes.
 From a user perspective I would not expect that (and personally
would not want to have it that way).
