Today I saw another reason for XCF to be taken more seriously as an
interchange format by the GIMP developers (or at least to document
the format and its effects better).
In rec.photo.digital somebody wrote in the thread 'IMatch cataloger /
workflow questions' about XCF support for a program called Imatch.
The poster would like to see this support, because he keeps edits of
his digital photos as .xcf files, IMO an altogether sensible use of
the format. And of course, a catalogue program should be able to deal
with XCF files then.
I am not trying to advocate XCF as a format for the exchange of
images, but I do think that if for instance the authors of
ImageMagick want to support it, they may have a good reason for that.
