The implementation maps VERSION_ID from /etc/os-release to the osVersion
key. Do you suggest to use VERSION_CODENAME from /etc/os-release
instead?

The spec [1] says about the osVersion description "The OS version,
typically corresponding to VERSION_ID in os-release". I am not sure if
we should osVersion in that case or introduce a new osVersionCodename
key.
