In my opinion extending bump stops to stop shockies bottoming out is a poor practice because although with the longer shockies you may gain something in the axles ability to travel further down you will loose most of it in the axles ability to travel upward.
I guess it depends on the whole setup of the car. with the tyre sizes we are running lowering bumpstops is a useful away of reducing the amount of guard cutting we do. Also, we don't tend to run very quick so we can run very little compression travel in the suspension.
There's also the relationship between travel and articulation. It's possible to achieve quite a lot of articulation with very limited travel so long as the bumpstops are brought under the chassis when the are lowered.
In terms of stability, it's a bit of a double edged sword. A car that's on it's bumpstops on articulation can be much more stable than a car that's at the same articulation but the car isn't on the stops, mostly because as drive load is introduced, the car does't "bob" or unload as much.
For a car with smallish tyres and bumpstops in the stock location, I agree that lowering bumpstops won't achieve much. For the way we set up our leaf cars, bumpstop spacing is a critical component.
