Not sure about the timing, but in case you have not got the message: we
should rather drop ElementTree from the standard library than integrate
unreleased changes from an experimental upstream repository.

Unfortunately, it hurts ET users if it ultimately leads to a fork, or to
a removal of ET from the standard library.

Please be EXTREMELY careful. I urge you not to act on this until
mid-March (which is the earliest time at which Fredrik has said he may
have time to look into this).
