Currently we have dumps in JSON and Turtle (.ttl) formats. It may be useful to have dumps in .nt (NTriples) format since this format is line-based and much easier to process with non-RDF tools.
Thus, I think it makes sense to create such dump in https://dumps.wikimedia.org/wikidatawiki/entities/
The feedback about the idea on wikidata list was largely positive.
In fact, since NTriples is subset of Turtle, we may want to phase out .ttl dumps eventually and have only .nt dumps, but this is not necessary to do in one step. It may be better to have both for a while to give people chance to change their tools and test them on .nt dump.
