Qualcomm has been beating the marketing drum on this instead of delivering. Ampere has delivered excellent hardware but does not seem interested in the desktop segment. The "greatest Linux laptop around" can not be some unmaintained relic from a hostile hardware company.
If you want to do a device, and your only chip option is Qualcomm I'd recommend not doing a device at all.
Can you see any other machine coming close to a Mac in terms of hardware quality and performance? Obviously the cost is silly, but while I agree with your sentiment, it seems optimistic to hope.
IME the Asahi support page is spot-on: There are a couple of yet-unsupported features (DP-alt mode being a big one), but any feature listed as supported will just work without hidden gotchas. I find this a big contrast to other devices, which will often "work" but have annoying little quirks here and there that are workable but can feel like a downgrade compared to Windows.
