now i could fairly safely assume that all QML KDE imports where hidden
under org.kde.* but that isn't the case anymore if you introduce
private.org.kde.*

It looks like you miss a part in the url.. I would say something like this:
org.kde.public.* = public imports
org.kde.private.* = private imports

But that would require changing all existing components to reflect this
idea..
