Ad 1. Fully agree, but we need to try to improve stuff here: https://github.com/fheng/best_practice/blob/master/nodejs/code_style.md

I think improving eslint rules may be ultimate goal here. Other tooling are just distraction and it would be quite challenging to keep them in sync and implement this across the board.
