Back when I used Eagle the "oh boy that's so many pins of signals I care so little about" was pretty much the only time I found their autorouter somewhat useful. The remainder of the time I was annoyed because Eagle being essentially just a vector-drawing program doesn't have (or didn't, at the time) push & shove routing which made tweaking layouts so goddarn annoying, in particular because the tools to move stuff around were completely trivial (i.e. they just moved the selected vertices and made no adjustments at all). KiCad is imho way better in almost every way than Eagle (in the versions I am familiar with).
I had that with the autorouter. I was doing a board that had one critical area, a custom switching power supply. The rest was slow signals. The switcher area had to be given a little extra space and some obstacles so the autorouter would do a tight job there. For the rest, whatever the autorouter did was fine.
I, too, am amused by how wound up some people get about this. It's a tool.
