Yes, taking the "data scientist" example as a "pure time machine
without touching, just observing" scenario, and the "programmer"
example as an "inspect and experiment" scenario, the addition of
this single sentence is sufficient to hint at the wide range of
usefulness to which this feature applies.  Nicely done.

I think this is short and thin enough to be good material to be
shared between the manual for everybody (which would want to cover
wider workflows with possibly thin coverage on some and thorough
coverage on others) and a survival guide for those who are lost
(which can be more targeted towards specific audiences).
