A company I have visited had, for some obscure reason, decided that teams should have their own fun/memorable names. Almost 2 years after implementation, every new hire's first comment was: "it's impossible to navigate the org with those names, we have no idea of what each team is doing". I could live with funny+descriptive, but for all that is good, funny only just does not work.
Yes, and we should change an entire companies culture to make a new hire onboard slightly faster /s
it's not just onboarding, a newer/more junior engineer is much more likely to misunderstand something and introduce a bug if specific context is required to understand the code
