There are issues with it. The collapse of the wave function by classical systems is a bit mysterious and it does lead to problems with there being nonunitarity. The CI shares difficulties as do all other interpretations. Curiously the CI is a decent way to look at D-branes. Of course the various string theory types that transform on D-branes are a lower energy asymptotic expansion of "something else," so who knows where this might go. At the Hagedorn temperature strings join into long strings and D-branes probably exhibit a phase transition to becomes strings that join up.
