Sorry, but this is a sucky move.
It will be more incentive still to move away from Invision and will likely dissuade new users looking to easily, cheaply and rapidly implement Invision with some customized functions.
Now you'll need to pay out of ear for custom development and be held in by the very limited devs experienced with this platform.
You'll also need to verify them yourself, somehow and you'll need accounts on countless sites to even try to facilitate those modules, coming from all different devs.
