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.


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
