I was suprised to meet it with no names. Is it all sites that go into public beta that will have Pro-tem moderators?
As per this answer regarding the process of launching a new site pro-tem moderators are chosen early in the life of the public beta
Appointing Pro Tem Moderators — A few weeks after launch, we start the search for “pro tem moderators” who will watch over the site prior to the general elections (when the site graduates). This process may take awhile depending on how clearly candidates emerge from the early community, and how amenable they are to taking on that role. We try to appoint three candidates in the first round, but we may start with fewer and appoint the rest as soon as we can if the process drags on too long.
As such there will be a short time in public beta during which the stack exchange team are still acting as moderators
