The advantages would be that we get the export done automatically and that we could write in Rust, e.g. with restricted visibility. But we could need `#[inline(never)]` (or ideally `#[used]` if it could go on functions) or `#[no_mangle]` (but we would lose the mangling). Anyway, the simplest is to export the original symbol, but we could consider to provide support one way or another for this kind of "helpers" (i.e. leaving the current helpers as those for macros and inline functions), so that it is clear what symbols are only exported for Rust use (and not other C code).
