It might still be good to do it in a separate branch instead of master, and to merge it after substitutes are available. Since "guix pull" takes the latest commit from the master branch, users could otherwise end up with a world-rebuild commit without substitutes. So maybe we could have a time window, but also discuss and prepare before- hand which big changes we would like to push? Having a team or a dedicated individual (in both senses of the terms, a designated person with a lot of dedication) to shepherd this through would also be good. Andreas
