I wish the author explored CFS first, because not only is it simpler to understand, it's also the scheduler that the kernel ran for decades before switching to EEVDF.
Exploring CFS would also naturally lead to exploring its limitations (like why its bad for desktop interactivity), and so EEVDF can be organically introduced into the picture and we'd understand and appreciate it better.
I'm too triggered by wording that signals it's written or at least modified by an LLM these days
