Features cannot update the names of roles

Features stores Drupal roles as their string name, not their ID. This is so that they are in theory exportable (like Views, variables, and - when enhanced by features_extra - blocks and vocabularies). Naming something by a machine name rather than an autoincremented numeric database ID allows

However, the only information carried with a role is its name! Therefore, trying to take a role name change from one site to another results in the following:

reverting a feature creates a new role with the corrected name (with no permissions), leaves the incorrect name behind, and hangs the status of the roles section at "Overridden".
