It does have some sort of meaning when it comes to pay grades as well. When I worked for local government I had the title "Programmer" and couldn't be called "Developer" without my pay being bumped significantly. People outside of the software world also seem to take the title "Engineer" a little more seriously than "Programmer" or "Developer" from my observation.
