Hi Boris, The "Governance Artifacts" are usually store inside the governance registry space. Therefore we don't allow to create the symlink for the governance artifacts from out side the /_system/governance(this is a limitation). Because creating symlinks from out side the governance leads to unnecessary bugs. This decision was taken to fix the issue[1]
