I know the EclipseP5Exporter has technically been replaced, but according to the wiki, its replacement doesn't do exports yet, so I still need it.

Why does the exporter package so many .jar files into it's output? Neither the in-app Processing exporter, or the default mac app exporter in eclipse do that.

My guess is that they're there in case Java isn't installed on the target machine.
Can I remove these from the lib folder for the exported exe without messing something up? 'These' being everything except core.jar and <myAppName>.jar  .
