There's still a very high chance for mod drops in the "reward" room of Void parkour rooms. And, statistically, the more drops that are possible, the more chances for rare drops. I usually get around 8 mods from a reward chamber of one of the harder courses (The one with the bridge, or the longer one with the laser pit), and I find often one of those is a rare. Typically, they offer a faster rate of mod retrieval than killing enemies. They're also where I've found all of my reinforced/rare storage containers in the Void.

However, this is NOT the case for Derelict treasure rooms. There is pretty much no chance of getting any kind of mod from those. The only potentially valuable reward from those is a slightly increased chance of a rare/reinforced storage container. I find that they're still worth doing, just to get more chances at those Mutagen Samples/Orokin Cells/Neurodes that are painfully ellusive. But if you're good on resources and Forma, there's pretty much no reason to do a Derelict treasure room.
