When a new environment is created, a disabled v1 config is automatically created for every existing flag in the project. Environment deletion is not yet available via the API. A future DELETE /projects/{projectId}/environments/{envId}?force=true endpoint is planned — it will require the environment to have zero active flags before proceeding. Until then, contact support to delete an environment.
