Well, that is why the primitive \primitive exists (and the alias
\pdfprimitive): so that you always have access to all primitives
in the engine (well, unless a smartass package would redefine
\primitive and \pdfprimitive, of course).

That virtual "you" will not be using all of these packages, and
even if that "you" would do so, I still don't see a *practical*
case for each of those packages having an *actual* clash with
*any* primitive. The whole name conflict thing has been virtual
so far, with the only person actually affected: Hans himself.

Let's be clear on this: we will not start prefixing every new
primitive with some random string, and I believe we have explained
quite thoroughly why we will not do so. We have heard all the
arguments in favour of prefixes before, and we are still not
convinced.

Best wishes,
Taco
