Comment 9 for bug 1563448

Ideally we should have an entry in the documentation for Liberty that describes the difference between using using the mechanism that was default in Kilo and the default in Liberty and why the default was switched. There should be a release note pointing to this documentation. Perhaps the doc entry should be in the upgrade guide? I would think that a deployer may choose to stick with l2pop at their own risk and the documentation should describe how that can be done.
