It seems to me that any "datatyping" solution that pushes interpretation
above that line is not actually doing datatyping, just providing a
more explicit interpretation of literals as strings than presently
provided by the MT.

The whole point, as I understand it, of doing datatyping in RDF is
so that the graph would be free of application specific interpretation
insofar as the denoted values are concerned so that we would have
greater interoperability between different applications and greater
portability of knowledge.

If a given proposal pushes responsibility for interpretation to
the application, such that two applications can arrive at different
interpretations, then that defeats the whole purpose of trying
to achieve a datatyping solution for RDF, no?
