This directly affect model flyers and was published today by the CAA.
The first link is to a very brief overview.
Links within this take you to the Call for Input document then the Online Response Form. It is best to read them in that order.
I have only skimmed through the Call for Input document so far and can see mentions of model aircraft and remote ID.
I'll post more once I have a chance to study oth documents.
