Whilst the vbulletin.org community has always been very active, its users represent a very tiny percentage of vBulletin users generally. The vast majority of customers do not modify their boards at all, and that has always been the case. People who modify their forums are a significant but small minority.

A basic hook system has recently been added back to vB5. Reality is though, there hasn't been much interest. Repeated requests for input on hook locations get roundly ignored. So it's not really gained much traction.

Look at other platforms and the market for free modifications has contracted considerably. Most coders are now only interested in what they can sell. There are multiple and complicated reasons why that's happened, but it's the way the market is.
