This only works for me2me hosts. IT2Me hosts currently only get the host-name.
There is no host-version info available in the response that we parse:

As long as we clear the host version for IT2Me (rather than, say, leaving the
version of the most recent IT2Me host), then that's fine for this CL. Can you
file a bug for adding host version information or IT2Me?
