I've made them for my Unisaw from Baltic birch. I have, perhaps, a half dozen and all are marked for the nominal dado width.
You don't need one for "EVERY" width of the dado. e.g. A nominal 3/4" plywood is really 23/32". If you make a ZC insert and then cut a 3/4" hole for the dado, this one could also be used for a 23/32" dado cut.
When making your ZC inserts or throat plates, keep in mind their final use. You are not going to be cutting 2" deep dados. More than likely, the maximum depth of the dado is probably going to be less than 3/4". As you raise the dado blade through the ZC, be aware that you don't have to raise the blade much more than the 3/4".
Use the right tool for the job.
