  Absolutely, in this context a change of the RDF dump implies a change on 
wikibase output for Special:EntityData and RDF formats.

  Quoting RDF 1.1 Concepts and Abstract Syntax - 3.5 Replacing Blank Nodes with

  One could also argue that this change may lead to a positive outcome as it 
allows the possibility to use these skolem IRIs.
  
  Additionally "unskolemizing" these IRIs is a trivial step that could be added 
to any import process reading the wikibase RDF output and willing to switch 
back to blank nodes.
