What issue do you mean? If it's about the "problem" of collapse most consider this to be the resolution. I'm the opposite, I don't see how it doesn't instantly resolve this whole "two evolutions" problem. Collapse is mathematically just a generalization of Bayesian conditioning. I don't really see the "issue" as such.That's what I mean; I really have never given it much thought and I don't see how it'll shed much light on this issue.
