I’m not convinced that we even need (3) at this point; I’m not quite
sure what this would buy us, especially as I don’t think any browser
currently deployed use that sub-level framework, and that W3C Widgets
don’t refer to them either.

Looking at Nokia’s security framework for widget runtime engines:
it looks like the capabilities are very coarse (e.g. lumping together
any kind of “user data”), which wouldn’t match what we have currently
defined in our APIs, and would in fact go against our minimalization

I think that this defect is likely to happen for any sub-API granularity
(which I understand capabilities are).

I’ll take a stab it (hopefully this week), but be warned that
capabilities may be a casualty in that process :)
