On the heels of fixing #8276 (closed), we should get rid of the remaining static flags. For the remaining cases, there's no real reason they should be static, other than changing them is fairly invasive and will require some refactoring.

I'm making this a goal for 7.10, since we only have 5 flags left (and a lot of the changes for them are overlapping, so fixing one will probably go a ways towards fixing the others.)
