However, I installed it on my M2 Air last weekend to give it a spin, decided it’s not ready enough for a Linux novice such as myself, and uninstalled it all pretty easily. It doesn’t mess with your macOS install at all. The only thing you need to be careful with is deleting the correct partitions.
I installed three times. The first, I didn’t give Asahi enough drive space to be all that useful. The second time I decided that I wanted to try KDE instead of Gnome. Those two uninstalls went without a hitch.
The third uninstall, however, I must have been careless, because I had to reinstall macOS through deleting a wrong partition. It wasn’t a huge issue for me, but it’s possible to do.
