quoted from mbien : /friend APIs are APIs which are not stable and
therefore not public. If you want to use them anyway, you have to
pretend to be a friend and use them. Since they can change from release
to release, you have to do provide a build for every release/

As those 3 APIs are very important part of a Language support module
they need to be made available to allow plugin developers to work with
them more smoothly.
It is now several years since those APIs are not public if i am not wrong.
I worked with them recently and didn't noticed any instability or harm
to the IDE.
So what is preventing to made them public ?
