In addition to the things you mentioned, I'm also quite happy about the existence of a party containing many young, inexperienced members in the government. They seem to be reinventing the wheel at least partly out of ignorance of the way things have always been done in German politics, and while that does lead to some chaos within the party, in some cases they're reinventing it for the better.
Even if they don't manage to push through any meaningful changes at all by themselves, their mere presence seems to be enough to shake up the traditional parties, and show them that they need to be more open and inclusive towards the general public, and particularly younger voters.
