Definitely. The proposed API is already aligned with the draft security
document (in its second iteration) that is not yet shared with the WG, but
it's imminent (pending WG/IG member announcement of the author). As agreed
in the last Scripting TF call, I will update the Scripting rationale.md
document with current information on this.

First we need to clarify actors, threat model, then move on to
identification, authentication, access management, integrity (data and
comms), security policies etc.

Actors include end users, solution providers, hardware manufacturers. We
also need to be able to identify/authenticate a Thing and a WoT Runtime.

The threat model takes into account the use cases needed in WoT. So the
first thing to get right in the WG for covering security is a set of use
cases that involve the actors above.

This would be tremendously useful. Again, we need to elicit
- use cases
- actors in use cases
- threats
- threat mitigation options
- and only then move on to weighing which protocols and technologies to
support in WoT.
