The Asahi maintainer resigned recently. What that means for the future only time will tell. I probably wouldn't want to make a big investment in it right now.
Your wording makes it sound like it was a one-man show. Asahi has a really strong contributor base, new leadership[1], and the backing of Fedora via the Asahi Fedora Remix. While Hector resigning is a loss, I don't think it's a death knell for the project.
