What is the purpose here? You are still stuck with a full blown MacOS running the system no? That is what Asahi tries to replace, not the other way around.
It serves the exact same purpose that WSL does in Windows.
You can run any flavor of Linux you like in a virtual machine, while booted into the native OS.
The purpose is to be able to run a decent Linux setup while also having MacOS for things. Not everyone is stuck on the anti-Apple train; some of us put software on all the platforms and thus using the hypervisor for this use case is quite comfortable. Disclaimer: personal experience - I too use UTM for highly productive things..
I'd recommend reading up on it, and perhaps trying it, because it's very useful.
For folks lamenting that the (awesome) Asahi efforts are challenged by reverse engineering of changes from M2 to M3, and so on, those changes vanish into the abstraction, but their benefits do not. That's why i switched from Asahi a couple years ago to UTM in apple silicon hypervisor mode.
