Jonathan,

 No, the CRC is just being practical. Look, imagine you're sitting at your seder and you spill some charoses on your shirt. You then take some matzah, scoop the charoses back on the matzah and you're back in business. The only problem is that you might thereby ingest the starch from the shirt. What, this never happened to you?

One isuse Jewcy readers should not overlook is pet food. Many pet foods are edible by humans and may contain chometz. To be safe we substituted matzah for the cardboard that our gerbil usually knaws on. We discovered that our gerbil found the matzah and cardboard indistinguishable.
