Its not quite that easy to add more space. RAIDZ and RAIDZ2 pools don't support expansion yet, so you have to be using mirroring to achieve expandability. And when you are using mirroring you have to add 2 more drives to expand an existing pool. Even when using mirroring I don't think you can remove drives like you say.
