Obsession with impact
Sadly, this is a side effect of "promotion-driven development". The performance theater mandates that to advance, you demonstrate impact, preferably measurable as something which is not trivial. As there is only so much "organic" impact you can make in a business doing "business things", there is an entire side quest of developing stuff which is not strictly necessary but can be used as casework for a performance review. When the promotion is achieved, the "stuff" which was often a solution looking for a problem, is abandoned, deprecated and then just dies a slow death.
Artifacts of those developments might linger in an organization for a while and sometimes be actually detrimental to core "business things" as the "not trivial" clause slides over to "proven in production". Then a few months or years later, the person who initially wrote it, got their promotion and is nowhere to be found. Now it's your problem.
