I always played X-Wing and TIE Fighter with a mouse and keyboard.
I can almost guarantee that had you played those games with a joystick, you're experience and enjoyment factor would have been increased significantly. I tried using keyboard back in the day on Wing Commander games, it's the difference of night and day. If BW does support joystick, I will be owning the keyboard turners and users.
Note to BW: Please make sure to add Pitch and Yaw controls for speedier turns for dogfighting. It's kind of a requirement for "aerial" combat.
