Question: Would it be worthwhile considering WebKit over V8?

JavaFX already includes the WebKit-based WebEngine [1], which provides
"two-way communication between a Java application and JavaScript code," in
addition to rendering web content. Depending on only one native engine may
ease maintenance costs and additionally reduce download size (at least for
the JDK, given Jigsaw).
