That's not exactly ubiquitous. And we have the self-estimate
src/lisp.h: CALLN is overkill for simple usages like 'Finsert (1, &text);'. */
which actively discourages using a C macro when you can use a direct
call.
Emacs C just is pretty far from a "non-issue". Pretending otherwise is
not useful. The number of people working on it will always be limited
to people comfortable working with interpreters and non-native data
types.
