The current UD practice follows the linguistic tradition: indirect objects are those NPs in double object constructions which bear the semantic role of a recipient or a benefactor.
so, for example, in the attested 12 (30), the 'closed' clausal conjunct should be analysed as a direct object, because the nominal conjunct, balance, is marked as a direct object (and the preceding NP, me, is marked as an indirect object): as is often the case with linguistic tradition, this traditional view confuses different levels of linguistic representation, namely, semantic roles and (syntactic) grammatical functions.
