Yes, that is minor but still important. Having 3 options: flag submission and flag discussion and flag title might be too much.

That's up to the admins to decide what needs more often to be managed, the submission or the discussion. Or it could be named:

    flag title | flag submission/discussion

> Yes, more power to the community. Wikipedia is still alive despite its massive openness. There just need to be enough trusted watchdogs.

Wikipedia has enormous meta community, and it's likely that such a huge amount of meta is toxic.
