Take a look at your BP next time you fly. It tells you when "boarding" starts and when it ends. That's the industry usage, and I would wager that most passengers are generally familiar with that usage.

Now it may be prudent to IDB pax before they've taken their seats, but the airline has a very good argument that "boarding" doesn't end until the GA closes the flight and/or the boarding door.
