That is my preference, too.

it's cStringIO vs. StringIO and cPickle vs. pickle situation again; the modules are 99% compatible, but there's always someone that relies on that last % (which is a result of ET being written in Python).

at this point, I think it's more important to guarantee that changing "elementtree" to "xml.etree" will always work under Python 2.5 [1], than to have a new set of potential subtle incompatibility issues. but I have changed my mind before...

  1. except for users that need a newer version, of course.
