I'm currently using the Pi harness as well, it's closer to OpenCode v1 with a few plugins. However, I have zero faith in their security or maturity after several communications with the CEO. Pi is also developed by an Israeli team, if that is something that matters to you, re: Mossad concerns or Palestinians rights.
I'm going to go back to my own custom harness and do a full rewrite, now that I have seen what 6+ other harnesses offer.
