Will Magento include any *.xml file I put in app/etc/?

Question

I was disabling the log_% tables when I realized it would be convenient to put the configuration in its own xml file. So I started looking for how the xml files in app/etc/ are included. When I couldn't find direct references to anything other than local.xml, and I know enterprise.xml is included, I tried an experiment: I added a properly formatted config file called 'nolog.xml' (below) and restarted Apache.

<?xml version="1.0"?>
<config>
  <frontend>
    <events>
      <controller_action_predispatch>
        <observers>
          <log>
            <type>disabled</type>
          </log>
        </observers>
      </controller_action_predispatch>
      <controller_action_postdispatch>
        <observers>
          <log>
            <type>disabled</type>
          </log>
        </observers>
      </controller_action_postdispatch>
      <customer_login>
        <observers>
          <log>
            <type>disabled</type>
          </log>
        </observers>
      </customer_login>
      <customer_logout>
        <observers>
          <log>
            <type>disabled</type>
          </log>
        </observers>
      </customer_logout>
      <sales_quote_save_after>
        <observers>
          <log>
            <type>disabled</type>
          </log>
        </observers>
      </sales_quote_save_after>
      <checkout_quote_destroy>
        <observers>
          <log>
            <type>disabled</type>
          </log>
        </observers>
      </checkout_quote_destroy>
    </events>
  </frontend>
</config>

Sure enough, my logs are still not getting written to. I'm just looking for a sanity check here: Can I put any *.xml file in app/etc and expect Magento to include it?

BTW, you shouldn't need to restart Apache if you've only changed Magento configs. You might, however, need to clear the config cache if it's enabled. — Luke Mills, Jun 05 '13 at 02:43

Yes, you can. It's part of Magento's standard configuration loading to look for any file named *.xml in this folder. Specifically, the following code does that.

#File: app/code/core/Mage/Core/Model/Config.php
$etcDir = $this->getOptions()->getEtcDir();
$files = glob($etcDir.DS.'*.xml');

Also, a too long for StackExchange self-link that covers more than you ever wanted to know about configuration loading.
