I think it helps to point out when something is an oddity that serves no practical modern purpose; the learner needs to know which are the "good bits" and which are the backward compatible cruft so they don't mistake one for the other.

Not necessarily. Teaching too much, too fast can distract a student from mastering each step; from properly “leveling up”. Teaching materials (including online courses like this) need to start with a theory of the learner in order to select and tailor materials for best effect.
