GIMP 3.0 should have Chromatic Aberration Correction and Highlight Recovery
gimp has no working Chromatic aberration correction, what is an essential for editing photos second essential is, efficient highlight recovery, fix/recover overblown areas
for 2.10 (and older) exist third party plugins for these tasks, which work well and so probably never somebody asked for it
maybe you look at Darla Purple Fringe (CA correction) plugin Fix Overblown Script-Fu plugin Change Shadow Highlights Script-Fu plugin
when this essentials are working Gimp meats your statement on Gimp's Home: "High Quality Photo Manipulation GIMP provides the tools needed for high quality image manipulation. From retouching to restoring to creative composites, the only limit is your imagination."
