Perforce workspace clutter

I am looking at the workspaces created automatically when performing a sync. The workspaces are created automatically, I would expect to see one for each pipeline, per agent, which expects to use perforce as a material. Since I currently have defined 5 pipelines and 1 agent, I expected to see 5 workspaces client specs defined. instead, I see 15. T10 for the server and 5 for the pipeline/agent.
