You mentioned that CAPS is scheduled for removal, could you point to some Mozilla info about that, Bugzilla, wiki, whatever exists?
References are very sparse, but CAPS for property access control is already dead, even though its corpse may still contract sometimes, see
https://bugzilla.mozilla.org/show_bug.cgi?id=453928#c0 for instance

How much of it will be left for the sake of NS?
Domain-wide script execution control. Notice that NoScript 3 currently does not use CAPS at all, though.

Nothing of declarative and user-facing, I'm afraid. A combination of page-level surrogates (or pagemods, or whatever can run user scripts before anything else) and Proxies, maybe.

[*] If not possible, I am curious as to why, since CAPS supports multiple policies.
It's a CAPS design flaw: even though CAPS does support multiple policies, if the same site is listed in two different policies the results are unpredictable. Therefore, you can use multiple policies as long as their site lists have no intersection (making NoScript generally incompatible with any other site-level policy).
