We received a lot of push back from even deprecating them, and the most that could be done was to add a comment to the javadoc dissuading people from using them and only keeping them around for legacy purposes.  Similar to how @New is stuck around, probably forever, any existing classes need to stick around forever.  When it comes to pruning, the pruning is around a technology and not just a small set of classes within a JSR.

Agreed, this is correct, and Antoine and I are aware of this and will make sure this is what happens.

Yes, if we decide to target Java 8.
