> _clearly_ spent a lot of time and resources to make third-party OSes viable on Apple Sillicon Macs. This actually isn't clear to me -- can you explain? Besid

  The open bootloader didn't magically appear one night in Apple's git repository. It boots in a notably different way than iOS machines do, and has some (AFAICT) pretty unique capabilities, including a fully-verified signed-boot of macOS partitions, while allowing third-party kernels at the same time. Asahi's "Introduction to Apple Silicon" [0], and specifically "Security modes, Boot Policies, and machine ownership" paragraph outlines some of that, Apple's "Platform Security" [1] whitepaper does too. Asahi's docs also explicitly state the same thing [2]. If you still don't think that shows significant amount of work and care were put into deliberately allowing third-party OS's to work on those machines, I don't think I can convince you otherwise.
