But then you're going from a cumbersome situation (where you have to

regular ElementTree).

Well, you can reverse the import so you're not relying on version numbers:

import xml.etree.ElementTree as ElementTree

try:

import xml.etree.cElementTree as ElementTree

except ImportError:

pass

There is a slight cost compared to previously (always importing the python version) and you'll still be using cElementTree directly until it's removed, but if/when it is removed you won't notice it.
