I believe that was part of Aaron's code that got reverted, yes.
Offline generation of hashes is definitely possible, but the only
reason you'd do it is to minimize the time during which some rows have
an empty hash. It's not strictly offline in that the text will still
have to be pulled from ES, but it can be done before the field is
added.
