The problem with that redefinition is that you spontaneously transform into an engineer when working on your own personal library, but as soon as you pull in a single dependency, or manually punch in some old school approximation algorithm, you are "just" some dirty good for nothing code janitor. Imagine somebody tasked with designing a bridge abandoning their engineering mindset because they used somebody else's drafting table. Also, that engineer better be "just" implementing other peoples algorithms on that bridge design - I'm not interested in driving across some 10Xer's suspension bridge.
