TL;DR: the problem if you just pass the DisposableStack that you're working with is that it's either a `using` variable (in which case it will be disposed automatically when your function finishes, even if you've not actually finished with the stack), or it isn't (in which case if an error gets thrown while setting up the stack, the resources won't be disposed of properly).
`.move()` allows you to create a DisposableStack that's a kind of sacrificial lamb: if something goes wrong, it'll dispose of all of its contents automatically, but if nothing goes wrong, you can empty it and pass the contents somewhere else as a safe operation, and then let it get disposed whenever.
