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
