When it comes to #interoperability there is no way around having consensus on what you interoperate on, and there must be alignment on some kind of Video related domain model that is robust and consistent.

If there were a robust #ActivityPub extension mechanism as well as good development practices and processes for the creation of extension into new business and application domains, then this mechanism can still facilitate app-specific extension on top of such a Video domain specification. It is very common for protocol design to have all kinds of extension points, look e.g. at #ATProto or #CloudEvents.

And more specialized domain extensions can also facilitate further extension in their design. Look e.g. at #ForgeFed AP extension, which allows custom forge-specific metadata collections to be sent with a federated Issue or PR.
