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.
You do realise that you are argueing for the creation of
\XeTeXsuppressfontnotfounderror
and
\LuaTeXsuppressfontnotfounderror
instead of just the single new primitive \suppressfontnotfounderror
that Jonathan and I came up with and implemented?
You could use \uniTeX as prefix for commands that affects both
"unicode" engines ;-). But a bit more serious: I do understand that
it will probably not possible to get a completly strict and
consistent naming scheme. But an imperfect naming scheme is in my
opinion better than none at all.
if someone has been using a macro package that provided a macro based
\suppressfontnotfounderror where that macro was a core macro, tnen
changes are high that it will still has its meaning (since it is defined
and overloads the primitive); the only thing a macro package then has to
do is provde a way to access the new primitive or just use the
\primitive prefix which kind of acts like a namespace for the engine;
actually \mymacropackageprefix can be easily define to create a package
specific namespace as well
macro packages have 25-50 K macro names easily so there's alway sthe
potential of a clash; in the end it's the manuals that tell users what
command to use
