Angle control can't be done using different ES.
The switch not only changes video, but any other associated stream. And that
decision must done at demux level.

That's exactly the same issue as when adaptive quality/alternative
selection patches which have been rejected and ended up with unusable
streams exposing countless ES to the user.

In the case of DVD angles, the change is seamless by design, where an ES
change can't be.
