Agreed.

I assume the answer is "yes," but are there compilers still in use that we
need to worry about and that don't support variadic macros? It's my
understanding that most (all?) of the widely-used compilers had
preprocessors that supported variadic macros even before C++ technically
had them in the language (probably thanks to C99), or are some
implementations broken in a way that it makes sense to simply declare that
they don't support variadics? Are there any plans to eventually just remove
the check and assume variadic support?
