MarsSeed [1] filed a deletion request for zfs-utils-raidz-expansion- git [2]: Just like its companion package, zfs-dkms-raidz-expansion-git (submitted for deletion: PRQ#48942): This fork of zfs is not developed since Aug 2022 (more than 14 months ago). [a] So it is not compatible with current Linux kernels carried by Arch.
