Roadmap to 1.0 ?

-EDIT

Are there plans to release a stable version of this module? Then it would have some 'security coverage' often needed in projects.

Open Issues (unsure if these need to be fixed before alpha/beta/stable?)
#3137200: Groups mapping doen't works when adding node translations
#3114431: Call to a member function addContent() on null
#3137202: Group mapping should be hidden when creating nodes from group interface

Also there seems to be some overlap with the https://www.drupal.org/project/gnode_field, https://www.drupal.org/project/group_content_field and https://www.drupal.org/project/group_mapping_from_node modules. The other two are also not stable yet. Maybe some collaborative effort to get 1 stable module out?

Or some documentation on how the modules differ from each other?
