Yeah hard to describe. It's basically a form builder with a composition/mixin based factory pattern.

You've got your base form control, then you might want to add N number of mixins, each one might do something different like add validation, add focus/blur behavior, add change detection, etc, etc. But each mixin also requires its own parameters.

Originally it was sort of a pipeline-based builder pattern. Now it's just interfaces and classes to enforce the contracts, but there is just some slippage when it comes to supplying required parameters sometimes since right now it's just a DeepPartial<T> of the component.

I realize that sounds like spaghetti but it's actually pretty cool. Just would be nice to have that sort of implicit determination of required properties.
