So, to make sure content identifiers are passed through correctly for cable
and broadcast would require an FCC ruling, pretty much?

Yup, all that would be great. Except the broadcasters don't actually
do that. They populate the PSIP feed pretty much with the same data
that is used by SchedulesDirect. In other words, if a program runs

Unfortunately, the broadcasters don't really have much incentive to
make this system work well, and in fact they probably wouldn't have
done it at all if they hadn't been compelled by the FCC (their digital
