MarsSeed [1] filed a deletion request for dolphin-meld [2]: Unneeded, broken minimally modded Dolphin, which is maintained in [extra] repo.
There exists a minimal Dolphin service menu addon, installable without root, to let users easily invoke Meld from Dolphin - as pointed out by @malcolm in a comment made on 2020-09-30. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/dolphin-meld/
