If there is no particle indistinguishability, every particle has a well-defined identity, then every particle has a well-defined trajectory.
Then even if no detector is installed, there is a well-defined difference between go-left and go-right in the double-slit experiment.
Then there will be no indistinguishability of cases, aka quantum superposition states.
