You're not holding it wrong. The problem is that this patch series introduces a backwards-incompatible change to the "sane_tools_path" option as it changes it from a string to an array, which makes Meson hiccup. Once Meson is not considered to be experimental anymore we should refrain from changing option types going forward, but until then I consider it to be okayish to break things like this.
From my point of view we can treat Meson as stable as soon as Git v2.49 is out. So from thereon, I will make sure to not include backwards incompatible changes anymore.
