The idea that IT should lock down editor configs treats software development like a factory line where workers should be interchangeable parts. Maybe it is, but I disagree. Software is a craft, and a developer's environment is an extension o fhow they think. If pairing is hard because of someone's custom setup, the answer is to use tools designed for collaboration, not mandating a specific editor config. Check out the code locally.

Personalized tools is how you eliminate friction, it'd be a misallocation of priorities to take that away.

As an side, vim definitely allows user scripts.
