Why aren't they official as of yet? If blizzard wants to show any support for the dota community, this should be incoming next patch. Makes as little sense as the lack of having an option to keep hp bars on all the time. I remember I used to stick a coin between the  keys or use the alt key. Ridiculous wasn't it? Inb4 Aduh uses mana bars. No i'm not, fag. But I would like to.
