The journal cannot tell an upgrade's prerm removal from an explicit uninstall, nor restore the previous enablement, so it must not trigger an automatic reinstall. Upgrades from packages whose prerm removes the Service are left unrecovered. Refs #8515 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
