I'm trying to understand what "RDF data that supports only plain 
literals and pre-dates rdf:text" could possibly mean.

I suppose that you could be trying to say

"As applications that support rdf:text may want to interoperate with RDF tools that
support only plain literals and pre-date rdf:text,  when exchanging
RDF graphs plain literals are replaced with rdf:text literals"

However there are no such applications (or at least none that satisfy the requirements of the
RDF recommendation).  RDF graphs and RDF syntaxes admit both plain and datatyped literals.  Any tool
that does not supportdatatyped literals is non-conformant.Further, any tool that does not support
reasonable XML Schema datatypes (e.g., for integers) is violating Design Goal 2.2.5 of RDF
(http://www.w3.org/TR/rdf-concepts/#section-use-xsd).  Any tool that does not support at least
rdf:XMLLiteral as defined by RDF is not really doing RDF - it is just doing simple entailment,
which is not RDF.
