I couldn't agree with you further, that is exactly the reason why if both of us feel safe about it and both of us are sure the airplane will land at the TDZ at the correct parameters the Boss will be ever so happy to see that loads of fuel has been saved and that the flight was perfectly safe.
I'm no rebel believe me, neither do I consider myself a "gifted pilot" but when conditions don't permit I have no doubt that the airplane has to be established AT THE LATEST at 1000'AGL! Otherwise, I always configure late but safe, saving a lot and not risking insurance premiums.
