Right on Flying Bull. In the utility world here in the states several utilities are trying to emulate the USFS methods for organizing and managing aircraft. They, for example always want marshallers anywhere you land or designated signalmen anywhere you place or pick up a load. It is kind of laughable, because the pilots for the most part disregard these untrained, or undertrained "designated signalmen".
The Marshaller, and designated signalmen are outgrowths of military culture where: the aircraft are typically huge and have poor visibility, the pilots are minimally experienced, and certainly not vertical reference proficient, and there are always a dozen people standing around waiting to do something.
In most cases both are unnecessary and can even lure an unaware pilot into more danger.
