The proposed IceCube Gen2 is mostly a superset and only slightly disjoint with IceCube (for example, I am not an IceCube collaborator but I am on Gen2...). But the point is that for experiments that are larger than a few PI's, anonymity of authors is basically impossible (since all papers have everyone on them).
