Event Id missing in the extensions.xml file generated by Studio

I'm currently working on a tool that displays a graphic containing informations found on the extensions.xml inside the Studio jar.
I'm facing an issue concerning the Events part. The xml containing the Event handlers part doesn't include the id of the Event (defined in studio).
Here's a snippet of the event handler part:
<handler chainId="ArticleFacet_EmptyDocCreated">
<event>emptyDocumentModelCreated</event>
<filters>
<facet>Article</facet>
<attribute>Regular Document</attribute>
</filters>
</handler>
But I'm expecting something like this instead:
<handler id="EVENT_ID_DEFINED_IN_STUDIO" chainId="ArticleFacet_EmptyDocCreated">
<event>emptyDocumentModelCreated</event>
<filters>
<facet>Article</facet>
<attribute>Regular Document</attribute>
</filters>
</handler>

Regards.
