Is that what will presumably be the template for the family ident?

The Family ident thing is a strange one. It’s technically for when multiple BBC services simulcast and need a single ident. The time for that would have been yesterday evening but there were no junctions, just solemn montages between different news presentations. The gold and blue family ident was used (in the proper sense) for the evening of the DofE’s death but then used on BBC One only for other Philip-themed programming. So if BBC One alone starts using a special ident for QEII-themed programming it would be more accurate to call it a ‘royal ident’ or something.

I'm in agreement, they would have had every service come together but they were all simulcasting the NC and BBC Three and Four were switched off due to statmuxing issues. 

Since BBC Two has already gone back to broadcasting its Curve idents, and BBC Three/Four looking like they will be restored tonight, it's accurate to say that whatever BBC One has later today will be the 'royal ident'.
