Do these stockfish's really know the position is drawn, or do they just have some hacked eval modification that equates a lack of progress to a draw.

PS: Moonfish ALWAYS searches all root moves as PV lines, yet not necessarily to the same depth, since I want to have a valid score for each line.
Does the one from https://github.com/joergoster/Moonfish work like that?
Yes.
Thanks, I'll check Moonfish out. I've been thinking that a smart MultiPV strategy like that could leave centaurs without a job, so I'm hopeful.

Surely, a search based result is more reliable than eval.
