Lucasfilm decanonized the EU.
Lucasfilm kept the film novelizations in canon.
The SW novelization established that the SW Galaxy was a modest-sized galaxy (ie. small-to-average).
The EU established that the SW Galaxy was 100,000 light-years in diametre (That’s about the same size as the Milky Way Galaxy, which is a huge, above-average sized galaxy.).
The nuEU recanonized the “SW Galaxy is 100,000 light-years in diametre” factoid.
