> We do - we state exactly what GIMP is and what we aim for

Respectfully, I just re-read the gimp.org homepage, about page, and FAQ. The only relevant passage I found is the FAQ where it states that GIMP is not trying to be a photoshop replacement (but that people regularly misinterpret it as such).

The first section after the recent news on the home pages says "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."

That seems clear enough to me about our focus, though one thing I've learned since I've started contributing is that whatever you think is clear enough, probably isn't! (Hopefully that doesn't come across as sarcastic - I mean it sincerely. I've helped out with writing news posts and been amazed at seeing how people interpret sections I thought were perfectly clear. It's been a learning experience!)
