Are we not distinguishing between vult "she wants" and velit "she would like"? In every other language I've learnt, the difference is important as the conditional is considered polite, but the simple present considered rude when making requests.
What do you mean by that? In the first person, certainly, "velim" is a sort of modest assertion, as distinct from the positive assertion of "volo". Any grammar will discuss this under "potential subjunctive".
