By robhudson:

When we add a compat override for a non-hosted addon (in which case we'd only have a guid). The update.py script doesn't need to handle this case as I think non-hosted addons have their own update URL, but it will still be used in the guid search where there is a section in the XML for compatibility that Firefox saves and uses.
