A few points:


 * A problem of limiting file types could lead people saving .jpg files as .png files, which should never be done.
 * .jpg images can still be great quality as long as they aren't saved multiple times. Plus they tend to have smaller file sizes.
 * .png files tend to be larger in file size, magnified with higher resolutions, for a different in quality that's not always observable.
 * Consider the viewer. A large portion of this wiki's images are only used in large galleries. Large images demand more from mobile devices.
