CDDL and MPL were defined as "free" only after a lengthy debate, and remain incompatible with the GPL - which, at the time, was widely considered the gold standard of free licenses. Without OSI as an ideological cover, they would have been ostracized even harder than they were.

> So why should a new definition have been needed to allow these licenses when they are already allowed by the old definition?

Maybe you should ask the founders of OSI? If their work was fundamentally pointless, why did they do it? Because it wasn't pointless, it was seen as necessary to be able to say "we are Good Guys, but not like them dirty GPL hippies".
