Not possible. Imagine the number of scenarios that require fixes. There are just too many of them. So you either end up with a gigantic amount of crystals (but still can't solve a problem in some exceptional cases) or you have a small number of crystals but a high number of situations where you can't resolve the problem with them. So maybe those crystals are more like app-configurations that we already have: you can tune things in a predictable way, but as soon as it goes beyond that you need to change the code.
