Also: When those processes that haven't been active since boot (and which may never be active again) are swapped out, more system RAM can become available for disk caching to help performance of things that are actively being used.
And that's... that's actually putting RAM to good use, instead of letting it sit idle. That's good.
(As many are always quick to point out: Swap can't fix a perpetual memory leak. But I don't think I've ever seen anyone claim that it could.)
What if I care more about the performance of things that aren't being used right now than the things that are? I'm sick of switching to my DAW and having to listen to my drive thrash when I try to play a (say) sampler I had loaded.
