Naturally luatex can add new primitives (and should do it) like
pdftex has done it. And you will never be able to avoid that such a
new primitive clash somehow. But nevertheless I think it would be
very useful if the names of the primitives would use an uniform
prefix -- even more as luatex is not stable and new primitives can
arise or disappear again. Prefixes like \pdf of pdftex and \XeTeX of
xetex create a simple namespace and enable package writers to avoid
_future_ conflicts with new primitives simply by not using the
prefix.
