Breakage of anything is probably the last thing I intended to achieve with
that patch. Maybe I misunderstand how tasks dependencies works, let me
describe *explicit* dependencies I did in tasks.yaml:

hiera requires deploy_start
hiera is required for setup_repositories
setup_repositories is required for fuel_pkgs
setup_repositories requires hiera
fuel_pkgs requires setup_repositories
fuel_pkgs is required globals

Coming from packaging realm, there is clear transitive dependency for
anything that pulls globals task, i.e. if task foo depends on globals, the
latter pulls fuel_pkgs, which brings setup_repositories in. I'm in favor of
reverting both patches (master and stable/8.0) if it's going to break
backwards compatibility, but I really see bigger problem in the way we
handle task dependencies.
