For the new 2010 dec/sf1 API endpoint, group codes are listed in the group metadata field. Concept labels are no longer used. Group labels (formerly concept labels) can be found in the groups metadata file, e.g. https://api.census.gov/data/2010/dec/sf1/groups.json
A listCensusMetadata(type = "groups") option could be added without much work to make this data more easily discoverable, particularly useful for the new 2010 Decennial and ACS formats.
Caveat: for most API endpoints the groups metadata currently contains no content.
