Asahi linux effectively only supports the M1 and M2 chips, so even a modern macbook air won't work, and even on "supported devices" you can't use thunderbolt or a usb-c display yet.

These use the A series chip, and even supporting new M chip revisions has been enough of an undertaking that I wouldn't really expect this to get Asahi linux anytime soon....

And apple can lock down the bootloader to be closer to the iPad/iPhone at any time with no notice, and based on their past actions, it would be quite in-line with their character to do so.
