It’s not so much that the pointer is not needed, but that it isn’t available so we have to figure out other ways to work around that fact when pointers would be more useful and allow you to write less brittle code.
Having to specify almost the same text for the name as for the expression, or reference the expression from the object script is brittle, and there’s no compiler help to make sure you got it all correct. What would be nice is the ability to have a pointer to the form control, and the ability to get/set the value using that reference (including updating the value in the bound expression). Sure, we can get by without it, just as we were able to get by without a built-in Form object and direct object property binding.
