Let's take airplanes as an example. 1. Do we start calling travel agents "aviation engineers" because they use airplanes to solve problems? 2. I sure hope the engineers who build planes aren't just winging it (ba doom pssh) 3. Context matters. Scientific knowledge increases over time, but isn't there a difference between willfull and unavoidable ignorance? If an engineer from the early days of flight were transported to SpaceX today, but they ignored the math and constructed rockets that we know with certainty will not fly, but they are convinced it will work due to sheer inner conviction, that's no longer engineering imho. Even if it may have been in their time, as long as they were using the known science of their day.
