FWICS libjxl-9999 allows building the gdk-pixbuf plugin for a long time already but the release ebuild forcibly disables it, even though the current releases seem to feature it. Why is that?
It is because the plugin require skcms library which is not in ::Gentoo. It the future releases, the plugin will work with lcms2 too, so we would be able to build it without unpackaged dependencies.

There is some work done to make the plugin to work with lcms2 only: https://github.com/libjxl/libjxl/commit/e2b6c75c3e25b3f7315128272bf3cd2a963bc9f5 https://github.com/libjxl/libjxl/commit/f1445661a56bcef52d0e46fa8fa4cbe4de9aeeaf However, GNOME developers wanted to use it in their flatpak build and even convert wallpapers into JXL format. They were unhappy with the speed and reverted the changes. Now, the libjxl developers are preparing new API and they are refactoring the plugin: https://github.com/libjxl/libjxl/pull/2827
Fixed in 0.9.1.
