I don't know if it would have to be available at all times even after the changes. Would that make or break it? People wait for it now, I'm sure they would wait for it. Plus, Frenilla doesn't have diketones. It should be offered for the mass of people who are concerned about it but still want to try your vanilla... only without the custard.
There are still trace ammts of diketones in Frenilla - much much much less than the other liquids though (below the industry standard ppm threshold but I still disclose it as a matter of transparency)
