Because anyone hadn't request it to be public.
If a function is a public, we can't change the API.
So we don't make it public until anyone request it.

Now you request, could you show the use case of rb_hash_clear() ?

Any reason for rb_hash_clear() not to be public C API?:

<pre>
static VALUE
rb_hash_clear(VALUE hash)
{
    rb_hash_modify_check(hash);
    if (!RHASH(hash)->ntbl)
        return hash;
    if (RHASH(hash)->ntbl->num_entries > 0) {
        if (RHASH(hash)->iter_lev > 0)
            rb_hash_foreach(hash, clear_i, 0);
        else
            st_clear(RHASH(hash)->ntbl);
    }

    return hash;
}
</pre>
