Overview of the Feature Request
For increased backward compatibility, the pull request to add support for multiple licenses in Dataverse does not add any other than CC0 1.0 - the 'CC0 Waiver' license that has been the only choice. For new installations, it probably makes more sense to default to a good set of licenses from the start to avoid admins having to do the extra work to set them up.
#7920 includes an API to add licenses and json blocks for the Creative Commons licenses in the format used in the API (json files are in scripts/api/data/licenses right now). This request would mean adding API calls to add those licenses as part of first-time installation of Dataverse.
Note: Whether all CreativeCommons licenses should be added by default, or whether other licenses should also be in the list is a matter the community may want to discuss.
