It's not, because the shelf is kept in the history. Unshelving needs to rewind the history so that tip points to the pre-shelve revision. bzr has no refs, so recovering the shelved revision after an unshelve is non-trivial. It may not be hard, either, except that for it to be reliable may require the bzr developers to make promises about internal storage management. Looms (requires an incompatible branch format) and pipelines (like Mercurial queues or Stacked Git) provide the necessary scaffolding.
