Dry run
Takesdry_run.
Names up to 50 subjects, with an optional expiry (in the future, at most a year away) and
reason. Callers who can manage access here may call it (Maintainers and above with the built-in
roles), and nobody can give a role carrying a permission or rank they do not hold themselves. A
subject that already holds the same role is reported as unchanged; one holding a different role
is refused. A service account can be given access only at its own group or repository or
beneath it, and never as Owner. With dry_run=true the answer says who would gain what, and
nothing changes.
