One of the reasons I always fought to have black from almost the day it existed was because (I thought) it would put an end to this type of petty human linting.
I have to disagree with the view that not using black means the lead is not senior.
Being senior means you understand the tradeoffs and you make your own decision.
If you ask a senior why he choose not to use kubernetes, you will get a bunch of real reasons. If you ask a junior the same, he won't have a good answer because he lacks experience with the pros and cons.
Right and “we don’t need to use black because we haven’t yet and things work fine” is a bad response that dismisses the real needs and concerns of others on the team when they’re saying “things aren’t fine we want computers to handle the nitpicks from here”. I wouldn’t say it indicates junior tech skills but it’s a sign of junior management skills.
