The paragraph Roll Control on the Spline IK page describes how to twist \ roll (*) a Spline-IK-constrained bone chain, but following the steps does not produce those results under the current release of Blender.

(*) "Twist" or "roll", meaning the dampened rotation that's inherited up the chain, creating a twisting effect like the one you get from bendy-bones:

A couple of things here, there is no supported way to do this. See this thread: https://blenderartists.org/t/how-to-control-roll-twist-in-spline-ik-rig-turns-out-its-impossible/598396/12 however like the documentation states you can chain together copy rotation constraints to create a twisting effect.

Great commit.
Is it possible to link to Youtube videos from the documentation? I wanted to make one explaining how to set up the Spline IK twisting à la bendy-bone, which is very useful for character spines like for head-turn twisting.

In theory yes, however, they cannot be from a third party channel and must be hosted by an official Blender youtube channel or video.blender.org

We are currently in progress on figuring out how properly do this.
