Linking to top level initial connections

[egekorkan]

In the F2F, there was a discussion about making forms optional so that TDs that are posted at #878 (comment) by @benfrancis can be more compact by reducing repeating forms. This initial connection would mean that every affordance uses this connection. I think that this solves it only for protocols that are WoT-aware, like WebThings. If we have something like MQTT over WS, we still need a way to link to the top level form. The attached slides explain why: https://docs.google.com/presentation/d/1CYaB0j6ltKH_m0O9LkBpGEgMvyFKgXoy7AMPe-c3k3A/edit?usp=sharing

Note: If wanted, I can copy them here but I wanted to make it separate to not clutter the issue.

That all makes sense. But note that making forms optional at the interaction affordance level does not mean that they can't be used, only that they don't have to be used where they would be redundant.

In a use case like the one you describe (using a non-WoT/non-web protocol like MQTT over WebSockets) additional metadata may well be needed to add the missing semantics.
