Are tag objects referenced by trees (and thus limited in scope) or are they stand-alone entities in the repository? The latter would be bad for shared object storages. Also, if I delete and recreate tags, will the old tag remain in the tree or will the file in the object storage disapear? So far all objects were always persistent, which is a nice property to have.
