yeah, i know this, debate can be also to set a specific installer to become a default on vBulletin... - we would simply have to install it by default, and use it for all the hacks... (i dream a lot!)
i comment about the HIS because i received comments from some of my clients, requesting me to install the hacks for them because they were not informed about the HIS and they were not very comfortable with any code... i suppose that a citation about the HIS installer inside the documentation made them fear the worst.. lol
anyway... this is not for me, but i'd like to see this fixed..
