In my experience, typically the junior's suggestion can possibly be done. However it often would be complicated to implement well, and I would be concerned how long it would take the junior to complete (if they would complete it satisfactorily at all). So, I agree with the suggestions that it is often more productive if a senior engineer suggests appropriate work.

Of course, I'm sure this highly depends on the individual person, the type of work, and the project itself.
