I faintly recall we discussed this years ago (the search feature is gone from the Vanilla forum).
AC is still easily the best solution for any 3D or 2D adventure game, but we're required to start each new project from scratch, with embryonic UI, input etc. templates. That has its obvious benefits and it does work. Still, in many cases more game-ready & polished AC modules would be a major help and project accelerator. And I for one would gladly pay monthly for seamlessly integrated new modules like that.
That said, it may be something that Chris was never interested in pursuing and that's why it's missing. Just my 2 cents.
