Well, primitives don't belong into a LaTeX documentation but rather into
machine documentation, and there it is at least mentioned. So to know
about deeper lying stuff, you often have to digg through the machine
documentation which mostly is not user-oriented, but more a technical
It also helps to read some source code of fancy packages (like fontspec)
that make use of many nice primitives (or now, LaTeX3 commands).
