Not OP. I'm a huge fan of Asahi and use it on my M2 MBP. There are some significant downsides in particular battery life is nowhere near what you'll get from MacOS due to inability to go into low power sleep state, and buggy DP alt mode for external monitors. I hope that will change but it's not there yet.

Because it still doesn't fully support all of the hardware on M1. I know it because I used Asahi while I had M1. Now I have M4 for work and it doesn't support Asahi at all.

I just use Linux PC as much as possible instead. And that 4$ M4 is just a fancy presentation computer I use when I travel.

Personally I would spend thousands on an actually great Linux laptop, but there are still none around.
