Hello!
We are working on a new update process for WDQS, based on a stream of
changes [1]. While not exactly the solution you are looking for, this might
be a building block for differential dumps. For example by aggregating the
stream of changes over a period of time.
Note that at this point, the stream of changes that we construct is
published to an internal Kafka that isn't exposed to the internet. If there
is enough interest, we might be able to expose it in some form.
Have fun!
Guillaume

Is there a mechanism in place for producing and
publishing delta-centric
dumps for Wikidata?
There's

Magnus Manske used to maintain some biweekly dumps as part of its WDQ
service, IIRC.
