If you don't recognize the kind you can't apply user preferences or attach the track to an appropriate UI element, but at least you could provide a menu of the labels, which would each be in the language of the track they label.

Label is not a fallback for kind. The label is a string that will be
used to create the text in menus of available tracks to provide users
with the possibility to turn tracks on/off interactively. It would be
provided in the language of the Web page and thus be part of any i18n
that the Web page authors do anyway. "Kind" in contrast is for scripts
and is not user exposed.
