Glad you are enjoying Arch. I agree, it is no longer hard to install.
Do you have an example of something in the Arch wiki that does not apply to EOS?
I mean, I guess most people self-installing Arch are not choosing Dracut (though you could and the Arch wiki covers it). I cannot really think of anything else though.
