User A wants to add B to his contacts. B receives a request with authorization, after answering which, user A also receives a request with authorization of user B in his contact list. It turns out that they must authorize each other in their contact list.

No way, this is the xmpp protocol, this option is only for clients.
Tweak the shared roster.
