Fix T62817: Can't drive modifier property with another one
Random place in the modifier stack can not be referenced, so it doesn't make sense to sue GEOMETRY component as a FROM operation. So now drivers on modifiers are driving GEOMETRY component, but are using PARAMETERS as a source for variables.
