Considering this change will be transparent to developers, there will be no compatibility impact on current implementations, and this is a good forward looking change, I agree with making this change. I will update the spec like so:

partial interface Document {
    enum VisibilityStates { "hidden", "visible", "prerender", "unloaded" };
    readonly attribute VisibilityStates visibilityState; 
};

I will need to update Section 4.5 Vendor Prefixes to accommodate this change. This change should not change the spec's Candidate Recommendation state.

Thanks,
Jatinder

Seems like it's a perfect fit for an enum: a limited set of values and so forth.
