Comment 3 for bug 1710850

This was discussed in the ironic meeting [1] and Dmitry, Julia are good with approving this without a spec, although the issues discussed in the meeting need to be mentioned here. I suggest updating the description to include the answers to the questions we asked, then ping us to approve this RFE. Thanks!
