Currently users can remove their current version of WP-Librarian and install a previous version. Considering WP-Librarian makes various changes to how it stores/handles data with each Alpha/Beta release this can result in things going seriously wrong. The worst case being a previous version of WP-Librarian overwriting the version in the database. This would mean, if the latest version were re-installed the migrations would be performed a second time.
