Yes, that's my recollection, too. I'm also a bit worried about the PyPI
situation, since pip doesn't automatically detect that a version of a
package is incompatible with the current version of python.

The etherpad Dims linked to [1] proposes looking at the PyPI stats for
client downloads. If those look relatively low, I would feel more
confident in dropping 2.6 support in the master branch of the clients,
with major version updates to indicate that.

On the other hand, how much longer will we be supporting Juno? A
matter of months, right?
