I have to know the exact names of the new primitive commands only if
I want to use them. To write a package that can be used with all
engines without a clash it is enough to know how to avoid the names.
That's easy with pdftex: simply don't use commands starting with
\pdf. It's also easy with XeTeX: avoid commands starting with
\XeTeX. But with luatex you are right. I will have to check
everytime a new version is released if there is a conflict.

Nobody is denying luatex the right to declare new primitives. The
only question is if the names of this new primitives should use some

What would this help? If it doesn't give an error now, there is no
way to know if it will give an error later.
