@ambitious-parrot-39602 I asked our team for recommendations, and they suggested you'll want to coordinate when using a namespace for experiments you don't want to collide with. Re-using a namespace is not advisable because, for example, 0-0.4 in a namespace will always have the same users going to that part of the namespace. So you can re-allocate those users once the experiment ends, but they'll be different from your general population because they have a history of being in this 0-0.4 part of the namespace (and whatever experiments were allocated to that part of the namespace).
