It's non-obvious to anyone (human or tool) auditing the code and not
knowing the special semantics of the macro.

This said we use the exact same construct in squid with a macro doing
implicit arg modifying on free, and in our auditing generally any direct
call not using the macro is considered suspect. I do not think anyone
working on the code have found this confusing even when we do not use
all capitals or other special form for the macro, safe_free(x).
