Other teams have probably already instrumented parts of the new editor experience that we care about, and could re-use for our own purposes. This task is about discovering those and figuring out whether things we need are already being recorded (or if there is code that can be revived to do so.)
One use case that stands out is Visual Editor, because we are interested in knowing how many new editors begin, but do not complete, their edits. Assigning to @JTannerWMF to set up the right conversations to figure that out.
Visual Editor is only one example, and there may be others.
