I am not sure if we should provide an automatic feature that hides all
pdftex primitives if people use e.g. latex. Maybe, it would be sufficient
to provide a TeX macro package that sets \pdfoutput to 0 and then sets
all possibly relevant control sequences to \undefined.

That way, people who just want to run broken code can easily insert
  \input hidepdf
at the beginning of the document.

This approach was suggested by David Kastrup (tetex-pretest mailing list).
