I don’t see it that way. An adult who becomes a Catholic becomes a member of the Body of Christ, you might compare it to becoming a new member of a family. Most of us live a life time, but how much is there to “know”.
New converts need to learn about Church teachings, sacramentals, saints, sacraments, Mary, the Mass, the Real Presence and transubstantiation, Vatican II, the Pope Bible history and Church history.
Equally important to the specifics of these things is our relationship to them. To be Catholic means we freely accept our responsibilities and obligations to our faith and to the Church herself. It is only right and proper that any individual taking on these responsibilities to be fully appraised of how they will bind them to the Church.
Using the the Creed as an example when we say “I believe” or “We Believe” we are making a vow as well as a confession of faith. If “I believe” I will do according to my ability. In that vow is an implicit statement of fidelity. How can I be faithful without ‘knowing’ my responsibilities? And, I would almost bet there is more to ‘faith’ than partisanism and sectarianism. If that were the case parishes could hand out banners and flags, “Go Catholic” You need to know, and unfortunate as it is, coming to know takes time, sometimes a life time.
