As much as I love the project, the work is far from done. Any macOS update can change the firmware of the GPU or the display controller, which would break the Asahi driver. And there are going to be a lot of macOS updates for at least the next five years.
I'm cautiously hopeful. Apple did break things a couple times already, but along with one of the breakages, they also introduced a new "we won't break this thing again" mode.
