Lack of removeTextTrack?

I was exploring the Text Track API the other day and noticed that although
there's a function to add a text track to media, addTextTrack() (
http://www.w3.org/html/wg/drafts/html/master/#dom-media-addtexttrack) there
doesn't seem to be any way to remove one, for example removeTextTrack().

I'm aware that there may have been a long discussion as to why this is so,
but it seems like a glaring omission otherwise.
