I implemented a PR to detect any dictionaries need merging during `interleave`: https://github.com/apache/arrow-rs/pull/8652. However it is only handling some simple datastructure like list of dictionary, or a list of struct, which has multiple dictionary fields. If the nested type get more complicated than that, then we need another improvement PR.
