Calabash is correct, the RCIA continues to allow "converts" to choose to take the route of "just learning the doctrines", and then undergo a ritual, preferably, on Easter Vigil, but can be done anytime. All depends on what process the local church has available. At our parish, we don't normally offer Calabash's process because it requires another curriculum and instructor. But if someone asked me, I probably would try to make provisions, and I am sure that our parish priest would comply. As I mentioned before, the candidates (who many could have potentially chosen Calabash's option) enjoyed the togetherness of the group, learning more about THEIR faith (which, of course, covers ALL Christianity, not just particular doctrines of Catholicism), and such. The small faith group and sharing with each other seemed to have a greater impact on these candidates then just a private meeting with the priest to learn about Catholic doctrines. They saw the faith of the group coming out, the work of Christ being made present. If a person was already quite active in their Protestant faith - but decided to convert, then I could see that RCIA wouldn't be necessary, as perhaps in your case. But many "converts" that come to us are not active in their church of origin, either.
In the end, it depends on the individual. Most Protestants who come to us were not overly active in their communities, anyway (otherwise, they probably wouldn't have come to us, they'd be happy where they were at). For them, the RCIA process is a good thing - I have seen how THEY have changed through the 9 months, just as the catechumens. But for someone already very active in Christ, I could see foregoing this process.
