Depends, Gaoxiong did a C&C and they were able to mostly mitigate the second order effects of C&C. Yes, in some sections some traffic was affected more, but apparently it wasn't widely disruptive. It can be done.

It helps when you can complete the project in a few years and not take a decade to build out a single line. So politics does have an impact on feasibility and practicality of C&C.
