Do you actually
know of a device that it would fail on?
It's not "irrelevent" what Mobi does if you wish to create source which can be built for both Mobi and ePub, and if ePub works without the graphics files being listed in the manifest section of the OPF file, I have to ask "does it matter, at a practical level?"
Standards are all very nice, but in reality one goes with what works. If web browsers, for example, were only to display web sites which rigorously conformed to HTML standards, there wouldn't be many that would work.
