I almost never use the function keys and I am a programmer. They made the right call on that one. Just because you use an editor that makes use of rarely used keys doesn’t mean that they are a universal truth.
Do you debug and use the keys to control it? This is my biggest gripe, since most IDEs (and browsers if web dev) map debugging to the Fn keys, so I end up using them a LOT. I hate clicking the debugging icons, particularly since I tend to use a few different editors/browsers and they are all in different spots.
First thing that comes to mind when mentioning the Fn keys is debugging, however I always found that is feels unintuitive to use and would be eager to change my habits to learn more intuitive shortcuts.
