To eliminate these data races, we can require that every global or static variable do one of the following:

is not clear to me if that's just a suggestion (as in, the proposal allows us to do this in the future and is very nice) or is the proposal adding these new rules to Swift?

Ah, it actually means to add these new rules to Swift. I'll clarify the wording to make that clear!

Shouldn't this be optional? Developers might want or need to protect globals/statics without actors (e.g. with locks).

We probably need to provide some mechanism for opting out. In earlier versions of the actors proposal, we had the notion of nonisolated(unsafe) to treat stored property as not isolated to any actor (therefore, acceptable from anywhere) but without any checking. That's one approach.
