What I was suggesting is that any change at all to the State Constitution should require a supermajority, by any route. No distinction between "amendments" and "revisions".
Adding, subtracting, or modifying the laws should require only a simple majority vote in the legislature and in a ballot initiative.
The Constitution is supposed to be the basic social contract, and should not be easy to change.
Given what has happened in Iowa and Vermont in recent days, and given that the CA Supreme Court has the opportunity rule that Prop 8 is a revision to the CA Constitution and not an admendment, the CA Supreme Court can align itself with the current trend across the country.
