Good question.
Maybe next Spring arch will remove it. I understand that this is when they do house cleaning,
The Maintainers of midori at arch are “Orphan”.
The best place to get some background is archlinux AUR midori-git. The second comment by eclairevoyant, dated 11-25-22, points to an archived web page that talks about the direction for Midori. It goes something like, get rid of gtk/webkit, code for mobile and then use electron for desktop. But if you look at midori-desktop at gitlab, the code has been removed. If you go to the astian.org download they have an appimage and a deb with no links to the source. The URL from pamac info midori-git URL gets a 404.
The biggest selling point seemed to be lightweight. Are electron applications lightweight?
An itsfoss article:
Attention! Discontinued Project
The Midori browser we knew and loved has stopped its development. It’s been merged with Astian project who has launched Midori for Android. There is no Linux port yet. For now, do not use Midori.
Midori: A Lightweight Open Source Web Browser
So no source, lots of 404’s hhhhmmmm…
