Mechanically the DH system works like the WFRP system where a character follows a well defined path (soldier, sergeant, captain etc). Each of the ranks in a DH career function as a career from WFRP, but they are all strung together without lattitude to move to another one. I would be the same as requiring that characters in WFRP follow one career progression tree and no other.
I think there are more 'elegant' ways to do it, but the current system reflects the opressive nature of the Imperium pretty well.
