Review Comment:
Re: `List<AuthorizationDecision> authorize(state, batchRequest)` - that
LGTM :+1:
Re: `AuthorizationDecision authorize(state, request)` - this method exists,
but it is NOT currently called.
Perhaps it might be best to migrate all authZ callers to use
`authorize(state, request)` first, remove old `authorizeOrThrow` methods, then
add batches, then revisit this PR. WDYT?
