I like this article

Thanks for posting it. I have read a few earlier versions of this paper and this looks like an even better presentation of the material.
But you don't mean to refer to the stages of the progress of insight do you? And if so, how would you correlate those stages to these stages of ego development?
My impression is that she is laying out stages of ego development, or identity development, and that she is identifying some very advanced stages which also include a greater sense of the openness/impermanence/constructedness of identity, and hence embody 'insight' in the sense of the progress of insight. But my understanding of the research is that it is also possible for folks at lower levels of ego development (i.e., less mature) to progress through the insight process and experience awakening without necessarily embodying the qualities of higher-level ego development.
