I don't understand what you are saying here.

In current RDF, two language-tagged strings are different unless they share exactly the same lexical form and exactly the same (normalized to lowercase) language tag.

The langtag-as-datatype proposal does not change anything about that. It simply uses another mechanism -- a set of special L2V maps -- to achieve the mapping between surface syntax and value.

What you are saying seems to be that the handling of language-tagged strings in RDF 2004 is broken. This may well be, but I think if we can produce something equally broken, then that has to be good enough.
