They are not using any CPU, and they are using very little RAM.
They make starting a query (taking a snapshot) a little slower,
but you probably won't notice that.
Their biggest danger is that there is no guarantee that they
remain idle, and if you have too many active sessions, your database
might have more work than it can handle.
