I disagree with this. The problem with lots of programming tools is the difficulty of judging which options are the best for your use case, before you have the experience of using them for a long time. So there is a real temptation to just go along with what everyone else seems to be doing; since they presumably know the benefits. There doesn't even have to be a real trend; it's enough when there's one in your perception.

I have certainly done quite a lot of trend-following myself. I have used relative line numbering in vim ever since I started using it, simply because the first person I ever saw using vim had that option active. Later, when I found myself doing mental arithmetic to get absolute line numbers, I was simply too lazy to make the switch. I have actually only just now gotten around to changing my config.

So someone who is thinking about switching to a ligatured code font might benefit from an article like this, if it turns out that the issues raised would be too annoying for them. If they don't think those will be a problem, however, they can just go right ahead and make the switch.
