One other point: basic practice among CBS Radio stations also has them also identifying the HD signals of their analog simulcasts. Even with AM stations.
It's not just CBS Radio practice, it's the law. The FCC requires that HD stations identify as such.
Not audibly. Unless something has changed in the last couple years, HD stations can ID visually on the read out of HD receivers. Speaking the ID is just a CBS policy that some others have adopted as well.

"Now, bear in mind that...for the moment...there's no such thing as an HD
Radio-capable tuner that does not have a visible display. So to comply
with 73.1201 a station does not need to *speak* "WXYZ-HD" as part of
their legal ID. They need only have the call letters with "HD"
displayed as part of the PAD/PSD on the HD broadcast (and that is
something that *all* HD tuners will do by default) because analog radio
listeners are not hearing a digital broadcast; only the HD listeners are.
This is also true for HD multicast channels; they need only include it
in the PAD/PSD, which makes it a lot easier to carry certain programming
since you don't need to worry about legal ID insertion to the audio stream."
