This list is quite comprehensive, but also quite boring. It's just a list of bugs and things that are suboptimal on Linux. You could write one about any operating system. Some of the items like 'such-and-such needs to be configured using a text file' are also not even real problems.

What do you mean by 'there goes your install'? There are multiple ways you could run bleeding-edge software before it's packaged for Arch. See for example every 'xxx-git' package in the AUR. Or Flatpak.
