Yeah, I don't mean to make it sound like there's no good reason for CV... I came across as sort of harsh. I just feel like CV got taken up in application a lot because it makes intuitive sense but with relatively little in terms of theoretical scrutiny, especially relative to other alternatives. When it has been compared to alternatives, the comparisons are sort of weak in that they often involve strawman or unrepresentative assumptions. CV involves certain assumptions itself, for example, in terms of choices, that affect results in sort of unpredictable ways sometimes. I'm a big fan of bootstrapping too and have often felt that that avenue hasn't been explored as much as it could be.
