Humm.  Fair enough I guess!

That kinda makes shape_plan a bit redundant.  Should we simplify the
shape_plan API a bit perhaps?  For example, have a version that only takes
global feature settings, and remembers those, such that executing the plan
wouldn't need passing in the features again?

Alternatively we can leave it as is.  I'm leaning towards this option.
