I see you repeating the same two arguments:
- it was implemented like this in the past and therefore must keep
  working exactly the same
- it might be useful under some vaguely specified conditions

Neither of these strikes me as a good enough reason to make major
changes to the API design. So again - can you describe a clearly-defined
use case that cannot just as well be handled by using multiple streams?
Empasis on "clearly defined", so not "I am sure we can find examples".
I would like to hear some of those examples. So far you have not
provided any.
