The answer to the question of order dependency is yes, it matters. The reason is that Pkg doesn’t want to change the version of installed packages on `add`.

However, this was determined to be quite confusing so in 1.4 there is a different strategy in place which should reduce the number of resolver errors by allowing current installed versions to change on `add` if they need to.
