I think in general a feature should require some amount of justification before being added. Right now the options menu is very heavily loaded with a ton of features that's even overwhelming to me when I open it. Imagine a new player opening the options menu and trying to figure out what everything means; it's quite the task.
I don't really have any particular issue with this specific feature, but I feel like the bar for adding an option to the stock version of FAF should be a bit higher than "a dev implemented it, so it's in". Is there any restriction to prevent feature bloat that I am not aware of?
