libsoup 2 is unmaintained so WebkitGTK decided to drop support for it in next release in March 2026: https://discourse.gnome.org/t/webkitgtk-is-removing-support-for-libsoup-2/31873 Since the package is security critical, we backport all updates to stable. Let’s remove it before branch-off to avoid breaking stable when that version is backported.
