I'd say this is a dirty little secret of the MLCC manufacturers.
You probably want to approach this "problem" with an engineering perspective: just because something is less than ideal doesn't mean it has to be fixed at any cost, or at all.
For example, ask yourself where those capacitors are typically used and see if valuation variations make a material difference.
I would also submit that anyone using a 22uf ceramic is most likely a nut job (or doing a nut job).
