I haven't been too successful finding the relevant thread. I remember 
Philip Lehman proposed a "poor man's namespace" for packages, but 
that's not really the same thing.

What LaTeX3 does currently is to rename all engine primitives to remove 
them from the user namespace.

E.g.,
  \write -> \tex_write:D
  \protected -> \etex_protected:D
  \pdfstrcmp -> \pdf_strcmp:D

So as far as LaTeX3 is concerned, it doesn't matter what the primitives 
are called :) But that's no help to the problem at hand.
