// If we hide columns the viewer can't see, they might think that the
// trigger isn't widely used and is safe to edit, when it may actually
// be in use on workboards they don't have access to.
// Query the columns with the omnipotent viewer first, then pull out their
// PHIDs and throw the actual objects away. Re-query with the real viewer
// so we load only the columns they can actually see, but have a list of
// all the impacted column PHIDs.
// (We're also exposing the status of columns the user might not be able
// to see. This technically violates policy, but the trigger usage table
// hints at it anyway and it seems unlikely to ever have any security
// impact, but is useful in assessing whether a trigger is really in use
// or not.)
