Thanks! After digging around the various Wikipedia pages I found https://en.wikipedia.org/wiki/San_Jose%E2%80%93San_Francisco%E2%80%93Oakland,_CA_Combined_Statistical_Area https://en.wikipedia.org/wiki/San_Jose%E2%80%93San_Francisco..., whose table seems to make it clear that the peninsula is all included in either the SJ or the SF MSAs. So they're not leaving out PA or MV or anything like that.
