zig's C compat is being lowered from 'comptime' equivalent status to 'zig build'-time equivalent status. When you'll need to put 'extern "C"' annotations on any import/export to C, it'll have gone full-circle to C++ C compat, and thus be none the wiser.

andrewrk's wording towards C and its main ecosystem (POSIX) is very hostile, if that is something you'd like to go by.
