If I had to guess why this course was retired in almost all languages even where the successor doesn't exist, then I think that it is because there is too much emphasis on PI Trusts, which can mislead the learner into thinking that this approach is still recommended. It is better for learners to search for guidance elsewhere than to have an easy guide in the wrong direction.
