dak@lola:/usr/local/tmp/emacs$ git grep CALLN src|wc -l
85

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.
