I am aware that v2 is already pending in experimental, but given the pace of transitioning to a new branch, it is helpful to have the rng.fill() function available faster, for packages to prepare for the transition, which is then in more cases possible to handle by loosenig crate depenency to ">= 1.9, <= 2".
Done,
Can you post in the bug for updating to 2.x when your packages are ready and I'll look at the rust team ones.
