NixOps arbitrary output


Is there interest in adding a resource to NixOps for arbitrary outputs (or JSON pointing to store paths)? I’ve been hijacking the network.datadogTags and putting non-datatag related json in there. This would be used for build outputs similar to sshkeypair, but could be anything. I’ve been putting paths to generated build reports and paths to generated crypto that I don’t want sent to machines, but want created for each deployment. I’ve got a sketch of it working almost in PR state, but I wanted to check here if this is duplicative, exists already, bad design, etc.
