I vote for accepting. Any objections from other maintainers?

Well, Jan still often uses mechanisms which are hard to check for malicious intervention replacing download URLs with manual/serviced package files. I don't like that much. Also I don't see that we have an issue here in games.

So I would oppose that request ATM for whole games.

As I don't think Jan is a bad actor, I've no problem with giving Jan maintainership of some of the unmainted packages he wants to care for.
