I've prepared packages and distributable for many enterprises and it's always CD as in continuous delivery not deployment, except on dev servers. A delivery may be a zip archive run via bash or powershell, or more of traditional msi packages and if necessary installed as part of the build pipeline. But remember, delivery means the package is delivered, it doesn't have to be installed.. But it could, and I've built releases this Week alone that large government agency here has allowed me to deploy as it contained just the change they needed.
