There is already a large body of code that mixes text and binary data
in the same type. If we have separate text/binary types, then we need
to plan a transition period to allow code to distinguish between the

I disagree. Many programmers will be satisfied when they read a byte
string from a text file, print it, and see "Hello World". Much better
that we distinguish the two types, so that it looks like binary data
