Creating a lighter, faster wheel that only works with sort of cart your company builds might invite accusations of “reinventing the wheel” but often it’s just “doing engineering”
But when you need other people to work with your wheel it's much harder to find those capable enough/that want to deal with that. Also when shit hits the fan and the wheel reinventor left the company you're gonna wish you had a standard wheel.
Yeah I’ve seen solo wheel reinvention lead to frustration with people leaving. It should be group effort or at least lots of “teach the wheel” (can we switch off this analogy yet :p)
