Well, there are a couple of things there I would not agree with.
More weight transfer with softer springs? Not significantly. Weight transfer is mostly down to the acceleration/braking and cornering forces. Since you are probably driving the track the same each lap then these will remain constant as the setup changes. There will be a small change in the static weight distribution as the car rolls but that is pretty insignificant.
What will happen with the weight transfer is that it will be transferred to the tyres more slowly with a softer spring, this will keep the grip up for longer before the tyre overloads and goes into slip.
Less steering input required with softer springs? Probably not, assuming you go up by the same rate all round and the balance is constant.
In terms of cornering power, two otherwise identical cars, one with soft springs and one with hard springs will create more or less the same amount around a constant radius corner at a constant speed (this makes a few assumptions about tyre grip remaining constant etc). That is to say that when the forces are balanced springing doesn't really make any difference.
There is often an instant at the apex of the corner where the car will be balanced in this way. Mid corner performance is a big indicator of overall balance.
What we are aiming to do with suspension settings is adjust the "feel" of the car as it changes from cornering to accelerating and braking and cornering again.
This is why it can ultimately be a very subjective thing. One driver may like the feel of a soft spring, another may like the feel of a hard one.
Sorry I am rambling a bit here but I hope I have made a valid point.
