I had to quit coffee last year. Bad headaches the first 3 days, got back to normal after about a week.

One of the interesting effects I noticed, is that my energy levels are more constant. No more highs, no more lows. Also, and this might be significant, my anxiety levels decreased significantly (I'd often get a mini panic attack if I drank a bit too much coffee, which happened every few days).

The thing about constant energy levels happens with sugar as well.

This allows me to have around double to time I had before of productivity. In the past, I wasted a lot of time being tired because of the "lows" of coffee / sugar, and the energy during the highs was way more than required for my daily tasks.

Having a moderate level of energy, but constant, helps me be constant in the long run and able to have a couple more hours of good work per day.

Also, life with less anxiety and stress is awesome lol. Also, some slight money savings since I liked quality coffee.

However, I didn't notice a relationship between development skills and coffee. Maybe that some smarter people around are usually more health conscious.
