For me the reasons not to do this are:

* It shifts work from tutorial makers to developers, and it's the
developers that are already the bottleneck at the moment, we have many
people making tutorials. So developer time seems a more rare resource
at the moment.
* I have never seen such a system done well in other applications, the
few times I've come across it, it's always been pretty frustrating.
I'm not sure why, maybe it's just a coincidence and there are
applications (of Blender's complexity) out there that do this very
