a time-based approach sounds like a good idea indeed; if just for things
like ungrafting, which are considered extremely low risk. 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.
