It would be preferable that the module removes that attribute from the product detail page so that the customer can not add the product to the cart in the first place.
Indeed it would.

When there is only one attribute available it's relatively straightforward to link stock to an attribute on the product page and either display it or suppress it.

With two or more attributes on a product, it gets more difficult as the cart needs some knowledge of the selections being made by the customer. As the mod has its roots back in osCommerce and long before AJAX had been conceived, it wasn't really designed for this. But a few people have done things in this direction. Since Zen Cart 2.0, with attribute stock, is imminent, I have no plans to do further work on this mod, though it being open source, anybody else is welcome to do so.
