It would be great if each component can be imported and extended via the scripts. I have assisted a few people with writing scripts for components that are just slightly different from the available components. It would greatly minimize the amount of work if they can be extended in the script. For instance, the multiple-choice component does not allow bindable options. It would be easier to extend it by simply making the option fields bindable

If this feature is already there, then the documentation needs to improve.
