I concur with the request. In all the years (or even decades?) of using GIMP, I never experienced a need for .xcf files. If I wish to save full image information, I export to PNG. If I wish to continue editing later, I leave GIMP open and, if the computer is technically able to sleep/resume, put the computer into standby. Specifically for my workflows so far, asking me whether I wish to leave changes unsaved when GIMP exits has been a waste and counterproductive; instead, GIMP should have asked me whether I had unexported changes. This risks discarding unexported changes. Merging “export” and “save” would get rid of the issue.
