Okay.

But the people who work on them only ever construct classical, single-universe theories. Why? Because they think that the quantum part of the theory necessarily has to be trivial.

It seems odd to me that you say you don’t understand something and then continue to write without asking questions. A longer explanation of what DD is talking about can be found here:
