[SOLVED] Theme Features

Short answer is No.
However you can add a comment (a semi colon or ";") before them to disable some. That "features" directive is a non-PHP way to say "enable/check this features by default".
You can find the relevant code under theme_get_setting:

<?php
// Turn on all default features.
    $features = _system_default_theme_features();
    foreach ($features as $feature) {
      $cache[$theme]['toggle_' . $feature] = 1;
    }

   //......
      // If the theme does not support a particular feature, override the global
      // setting and set the value to NULL.
      if (!empty($theme_object->info['features'])) {
        foreach ($features as $feature) {
          if (!in_array($feature, $theme_object->info['features'])) {
            $cache[$theme]['toggle_' . $feature] = NULL;
          }
        }
      }
?>
