I see I should revert the comment I just added to py-cElementTree/DESCR.

Indeed, this is getting entertaining:
- as cElementTree is deprecated, gobject-introspection should be calling
  ElementTree
- gobject-instrospection still needs to depend cElementTree so that the
  faster implementation is found
- The default parser for ElementTree is XMLParser which depends on the
  pyexpat module via xml.parsers.expat. Debatable where that dependency
  should go - cElementTree? Just going for gobject-introspection for now...

Correct?
