There is a dropkey --batch, so I guess I could workaround but probably would be nice for consistency to have --batch mode for drop itself as well
done; went ahead and added drop --batch to be symmetric with get
Might be better to make dropkey do the same numcopies checking as

The benefit of keeping this in dropkey is that dropping by key

Only downside I see is that dropping by key is unable to honor
.gitattributes numcopies settings, since the associated filename is not
