MarsSeed [1] filed a request to merge webkit2gtk-unstable [2] into webkitgtk-6.0-devel [3]:
Only the latter PKGBUILD is owned and maintained, and its base name aligns with the pkgname of the stable Arch/extra/webkitgtk-6.0 package. The former AUR build is abandoned since a year ago, and is obsolete.
