Handling is much about the front and rear tyres grip limit and tyre forces generation. Those forces are basically proportional to the vertical loads on the tyres. So whatever you do to the working condition of one end, you want to do the same, proportionally, to the other end.
So in terms of handling, the important is to try to keep the front/rear weight ratio as designed for the bike. If you add 80kg on the rear rack, they won't have the same effect as adding 60 on the passenger seat and 20 on a tank bag.
And the limit, for me, would be the tyres. You have to consider not only the static load and the extra effort to accelerate or brake the bike, but also the load transfers during acceleration/braking. For example: an overloaded front tyre will saturate easily during hard braking, so it can slide.
