I guess my faulty argument about "loopcount=0 and loopcount=1 should not be the same thing" is still the crux of the problem here (though its not loopcount=0, it's "loopcount missing" we should be talking about).

LoopCount missing (resulting in a 'play once' behaviour) and LoopCount=1 should not have an identical result. If they did, we'd need to start a discussion with the image creation tool providers (ie, Adobe) to change they way they count at the file-creation end. This would result in some big issues for online advertisers as Total Run Time is strictly policed in banner advertising.
