Realistically?
Full wikidata is 16B triples. Very hard to load - xloader may help
though the goal for that was to make loading the truthy subset (5B)
easier. 5B -> 16B is not a trivial step.
Even if wikidata loads, it would be impractically slow as TDB is today.
(yes, that's fixable; not practical in their timescales.)
The current discussions feel more like they are looking for a "product"
- a triplestore that they are use - rather than a collaboration.
