I'm suggesting that the EFB producers may have been, like me, labouring under the same misconception about the demise of the concept. Why else would the mandatory broadcast areas not be depicted on the composite charts, when the producers have managed to overlay every other boundary on the composite charts.
Why don't you ask them?
As I said earlier:
Then I suggest you tell your EFB provider that
1.Broadcast Areas have been in place and charted for around 10 years
2.by omitting them they are presenting a safety issue, and
3.CASA will have an interest in their product omitting key operational information that appears on AIP charts.
