I imagine that most teams would save 1 lb, maybe 2 lb at most by switching to direct-acting. Can anyone really tell me that those 2 lb makes the difference on the podium? I think not...
Instead of settling in on the weight advantage, I would emphasize that reducing complexity/part count is MORE important because it potentially gets you off the workbench and onto the track sooner. This advantage is significant, don't underestimate it.
Adam,

You have hit on the 2 points that we found running DASD in 2013. We were trying to package the pushrod/rocker, and there was no real structure where we wanted to put things. But, we rotated the model around, and there was a straight line between the control arm and mount. Draw straight line, make a circle the size of DASD and done. As for the anti-roll devise, we had one designed, but not yet manufactured when it was time for first drive. So we re-calculated some wheel rates/anti-roll torque distribution, changed the front springs, and went testing. The car worked well enough that our drivers were always the limiting factor, so we left the extra bits off.
