Just remember - everyone's use case is different
As is usual there are multiple opinions here, seemingly based on "*I* don't think it's a good idea because..". But more power to the Asahi Linux people, I say. It gives me more choice, and if that's not attractive to you, well so be it.
I'm retired now, but a loooong time when I was working in a small office of mainly Mac users I was (and still am) a Linux zealot. So one day, as a joke, the boss handed me a brand new Macbook Air to replace my ageing Toshiba laptop (the business was very profitable, so could easily afford to do this. And all the Mac users thought it was hilarious!). I actually really liked the Apple hardware - the very early Airs were amazingly light and portable and had great graphics compared to my clunky toshiba. MacOS, not so much. So naturally I tried to install and run Linux, but ultimately failed to get anything working properly. And soon after the screen stopped working - maybe because the old X11 drivers had cooked the graphics chip??
Now I have a lot more time on my hands I thought it might be interesting to try Linux on Mac again, just for my own entertainment. But when I visited the Apple section of a computer shop I was really disappointed in the latest Apple laptops. For me their main selling point was lightness, but the latest "Airs" weigh a ton. WTH? And billions of pixels on an 11 inch screen are wasted on my old eyes. So I'll stick to my current Thinkpad, which is reasonably light, and has a good 1920x1080 screen. Runs Linu Mint and everything "just works". Fine for my more frequent travels.
To get back on topic, for me the best thing about Asahi is that in future it may save a few ageing Apple laptops going to landfill, and that is a "GOOD THING".
