Automatic correction by software has become common. The wide zoom lenses usually need it.
In the case of my Fujifilm 14mm on APSC(21mm-e field of view), the distortion is minimized in the optics...there is no need for software correction. I have observed this by blocking the electrical contacts from lens to body so the camera(and subsequent processing software) doesn't know which lens is attached.
My point is only that "it can be done", at least with a prime lens.
According to PT Lens, the Fuji 14 mm requires no correction. Very few lenses have this accolade.
