My feeling is this.
Shame on you Gimp.

"One man's meat is another man's poison." This is likely a design decision. Likely based on user experience, where people spend a lot of time image editing and then quit the program without saving. Oops.

It's pretty conventional to prompt to save changes when closing a program with unsaved changes. It would really worry me if a desktop program can close by autosaving, and then restore it back for next time!
Solution to skip prompt: Press CTRL+Q then CTRL+D very fast.

I can understand.
I once chopped a 8 inch diameter branch with a machete at my daughters house.
Because of my pain. I got about 30 minutes of pain relief and my son-in-law hid the machete.
The problem is, I get the prompt after opening a file without any changes being done.
But please do not worry about it.
So I use a viewer in that case.
