Hi,

My main worry was to not expose host related information to end users, but
noting administrators probably do what the information.

Looking again at the Stein spec we merged, the proposed policy rules
already take care of all that.

I think the next step is to re-propose the spec for the Train release. I
couldn't find it, but maybe you have done that already?

Thanks,
