It will become redundant and confusing once we bring the module system into JDK 9. The proposal in JEP 261 is to remove it and it seems saner to remove this in jdk9/dev in advance rather than trying to carry this in jigsaw/jake.

I looked through this change and I think you got everything.  Removing @jdk.Exported is okay.  Supported JDK-specific API is currently documented in modules.xml as an interim solution and it will be replaced the module definitions when the module system is in.
