There is no doubt that downforce is needed for a competitive pinacle of motor sport formula. The question is how much?
In my view the sensible limits are exceded when a corner like Eau Rouge which used to be a test for the brave 11 years ago can be taken flat out. High speed cornering on that level just increases the risks and the costs for safety measures at the circuits without contributing to the over all attraction of the sport. It can be much more entertaining to watch drivers go through such corners as fast as they can without full throttle.
I think your example is not very good. Eau rouge is taken about 20km/h slower now than the previous years for a simple reason, this is a power limited corner.
Should the cars be able to go faster they'll still have the downforce needed since it increases with speed.
The challenge of going through eau rouge, at least in the modern days of F1 has always been a steering challenge, since the challenge of the corner is the change of direction.
There is no skill in putting the pedal to the metal with downforce gluing the car to the track but there is great talent required to balance a race car on the edge of adhesion in a roller coaster like Eau Rouge.
I think you don't appreciate what is high speed driving. F1 has never been (in its modern incarnation that is from the 90's) about driving on the edge of adherence.
It is important to know that driving technics are totally different from a Kart to a low speed single seater till F1.
You never drive a F1 on the limit, always under it, your goal is to go as close as possible to that limit via fine refinements.
That fact brings the result that, for a given speed, reducing the grip aviable will always put less technicity in cornering performance.
That's why in F1 the goal and quotes from drivers has been "to go for grip" for a long rather than "carrying speed".
the aim in F1 cornering is to always find the best grip while in lower grip and speed series the goal is to maintain the grip to carry speed into a corner.
In thoses series you can have small slides, in F1 not.
Whatever level you want, as long as the F1 cars will corner as high speed (meaning that they'll have a lot of grip) the driving technique will always be fine tuning of the grip.
Sliding is dangerous and the cars are not done for that either.
Where i would agree with you, is cases where all corners would provide for a lot of spare grip, but that's not the case at all.
So in this context from an entertaining and safety perspective I welcome the downforce cut they did for 2009. Will it be enough and will it be on a level appropriate for the increased grip? We will have to see.
The ratio of downforce over speed is more appropriate. See example above, in 2004 the levels of downforce were higher than now, but eau rouge was more difficult to take.
My bet would be to put natural limitation on maximum downforce gains possible via regulations that limit the possibilities, that would switch then on the aero efficiency and downforce at low speed.
From a driving point of view i prefer having a lot of grip at high speed, that's funnier and requires to be more technical and precise.
But well, nascar style huge slides are cool too, but that works because they have banked turns.
