There is no "optional".

Yes, the question is what does "support" mean exactly. I'm afraid someone could claim that it does not necessarily mean "give the user a convenient interface to view and navigate the TOC".
Anyway, just above that it says:
"It is important to emphasize that these navigation features are intended as a convenience for users who want them, and not a burden to those who do not. The alternative
guide to the book may be provided for those users not requiring the navigation features of the NCX."
It also assumes the NCX to be present in addition to an inline TOC. Another advantage of an inline TOC is the possibility of controlling the style and appearance, which one can't quite do with NCX.

Note that, IIRC, the "name" attribute is deprecated, use "id" instead for ePUB (and it does not have to be in an <a> element, you can have <h1 id="01">).
