You had better cache glue As, as long as they are tagged as glue As with a domain name of query. Then, the cached information may be used as glue in additional section but not in answer section. It is not a problem if a glue A in additional section is cached and reused as a glue A in additional section to similar query. > As a matter of fact, it never occurred to me to wonder at this > misbehaviour The misbehavior was present because most, if not all, implementations cache both glue and authoritative answers but did not distinguish them by appropriate tagging. As I have been warning on the problem for these 15 years, some implementation may hopefully be fixed.
