fcf5d11c63
The use case of this field is mostly to support -J combined with --json. When that is implemented, a user will be able to look at the field to determine which of the requests they have sent it corresponds to. The field typically has a single value in its list, but in some cases mutliple values (eg 2 command-line params) are combined together and the list will have more. Note that json parsing was already non-strict, so old git-annex metadata --json --batch can be fed json produced by the new git-annex and will not stumble over the new field.
