What did change was the explicit exclusion of people outside of those qualifiers.

That’s not the point. Don’t focus on the logical conditions, because they have not changed.

As far as I understand it, the important change is the missing “Every”.

Before, the “every” had made this a guaranteed right. Now that is gone, and only conditions are left.

The right to vote could be taken away from some people by creating further conditions in the future.
