Yeah, that's my take as well (especially since, in 3.2 and earlier,
"forcing" use of the pure Python version was just a matter of
importing ElementTree instead of cElementTree).

While Xavier's point about lxml following cElementTree's lead and
using a factory function is an interesting one, I think in this case
the documented behaviour + pure Python implementation win out over the
C accelerator behaviour.

Cheers,
Nick.
