"Knowledge of cofinality is necessary to understand any OCF. Without a complete understanding of this term, many users experience a misunderstanding of how a function works."

Sure, but a beginner needs to learn to walk before they can learn to run.

You mentioned that your target audience are people who "justbegan to study ordinals". Such people are not ready to learn about OCFs. I mean, a person at that stage can certainly learn the expansion algorithms of a given OCF, but that's not the same as actually understanding what they are doing.

Ahis is the reason we get things like UNOCF. We have people who rush forward without laying the most basic of foundations first. They want to learn how to manipulate the symbols, but do not have the patience to learn what these symbols actually mean. Improper understanding of cofinality is just another symptom of this problem.
