As tordanik has already pointed out the main issue with the proposals is that there is no inherent ordering that can be deduced from level values on objects if they are not (integer) numbers, so any such scheme requires far more insight, effort and available context from joe-casual-mapper and joe-casual-data-consumer to get layering right. With the current scheme that is a no-brainer even if there are discrepancies between actual numbering of the floors and what is being used in OSM.
Simon PS: addr tags are for postal addresses I don't think using them as a level name/ref makes very much sense outside of that very narrow application.
