You are right. On googling a bit I found this description by Aaron Meurer in a March 2013 post:
"... I can tell you from Bronstein's book: - everything before chapter 5 is preliminaries, and was basically implemented before I even started. - chapter 5 is the base of the algorithm, and has all been implemented, except for 5.12. - most of chapter 6 is implemented. The exceptions are parts that require certain subalgorithms that haven't been implemented yet, namely the stuff from 5.12. - only a small part of chapter 7 is implemented. - none of chapter 8 is implemented. - the parts of chapter 9 relating to exponentials and logarithms have been implemented."
