MarsSeed [1] filed a deletion request for libmediawiki [2]: This has not been updated with a stable release since 2017-08-30. It's been dropped from the KDE Gear/Apps suite in April 2022. There is no reason to keep this package. There is an AUR/libmediawiki-git package, that receives occasional maintenance commits, so I recommend to keep only that and delete this obsolete one.
