Sure they have. The Star Wars Rebels cartoon is listed as being part of the official canon, and it includes many references to EU material, such as Sienar Systems, the title of Inquisitor, lightsaber forms, etc.
They really aren't though. They have pretty much thrown all of it out and they haven't really 'picked' anything to be re-instated.They aren't throwing it out per say. More picking and choosing what parts they want in the new canon.
Not to mention the new novels (mostly Tarkin) have already reconfirmed:
Carrack Cruisers
Dreadnoughts
Immobiliser-418 cruisers
Various fighters
Two other Interdcitor ships from the CC range
Victory-class
Various planets, events and characters that have not changed
So far nothing has actually been contradicted, and some stuff is already re-confirmed as canon.
Which EU fighter models have been made canon by the new novels anyway? I only remember models that were already canon appearing in them.
V-Wing, Delta-7 and Eta-2 were all from the PT, Z-95 appeared in The Clone Wars cartoon, and the various TIEs were from the OT.
