jessienab [1] filed an adoption request for redumper-bin [2]: Previous owner either deleted or orphan/abandoned the package. I currently maintain both redumper-gui-bin, and redumper-gui, so I'm familiar with redumper install and build processes. It would be ideal to have redumper-bin return, as many folks rely on a specific prebuilt version, rather than using git based builds.
Also, some don't want or need the gui version, ex. headless archival systems, therefore redumper alone from cli is still a necessity. [1] https://aur.archlinux.org/account/jessienab/ [2] https://aur.archlinux.org/pkgbase/redumper-bin/
