I also saw the note and, as we fly out of SFO frequently, I wondered as well. Before applying the update, I looked at a reservation for Saturday. Within the reservation, DFW and MCO had blue hyperlinks to a map. SFO already (pre-update) did not have this link. It may have had a map elsewhere, but it already seems to have been a second-class citizen.
Cheers.
The SFO map was under the Terminal Maps section found under the main page.
