Maybe a wrong function name (js_alter) in advagg_mod module

I'm wrong or the following code represents a wrong function name because the correct name of implementation of hook_js_alter should be advagg_mod_js_alter , also because advagg_mod_post_js_alter function it's never called?

Version 2.21 it's not affected by this bug

// Helper Functions.
/**
 * Alter the js array.
 *
 * @param array $js
 *   JS array.
 */
function advagg_mod_post_js_alter(array &$js) {
  if (!module_exists('advagg') || !advagg_enabled()) {
    return;
  }
