I don't think that this is a hard rule. They probably look for the same signs that we do - plausible sounding utter gibberish. They just don't want the drop in quality due to that. If an author creates content with AI, but takes their time to edit and improve it, I think that the Gentoo team may give it a pass.
This is a problem with how Haskell is packaged for Arch.
That's hard to recollect off hand. But one thing I find easier with Arch (and Gentoo, which is my daily distro) is to create complex partitioning schemes (e.g encrypted swap and btrfs subvolume mounts) and boot loader configurations.
Another example is a window manager with a somewhat complex display manager setup and a ton of supporting services.
PS: I don't consider Arch to be the silver bullet. For example, I always prefer Debian for servers.
People favor Arch Linux for configurability, not lack of bloat. With the level of configurability that Arch offers, any DE can look bloated. On the other hand, if you are a new Linux user or someone who just wants to use the computer without so much personalization, anything Linux offers is lightweight enough. Even a decade old system has enough hardware to handle modern Linux distros effortlessly. This is probably what a regular user wants anyway.
Here's one issue they hope to solve with this rewrite: https://github.com/fish-shell/fish-shell/issues/238
