You miss the point. MPEG defines levels exactly so that bitstreams can say "you need to be level X to be able to play this" and players can implement "up to level X" and interoperability is well- defined and assured. Levels *improve* the interoperability, not make it worse. Without formal level definitions, you never know for sure what you can 'get away with' in your encodings if you want it to play on a set of devices.
The flipside is that even if you've got the latest and greatest Mac Pro, if the content oversteps QuickTime's profile support, the video won't play.
