Feature: Review disabled and readonly in each component's angular formControl and layout / styling #3671
Description
Each component can have an opinion on how the angular formControl and the layout / styling in that control handles disabled and readonly.
A disabled formControl does not include its value in the aggregated form value.
A disabled form field can display as the built-in disabled form field interface, but could also display in other ways.
Same for readonly.
Special note: A disabled formControl in the GroupComponent and RepeatableComponent means that the model value is not included in the form model value. This is how a GroupComponent can be used to group components that do not have models, and no empty object is included in the form value.
This is either not yet implemented for some components, or not fully implemented.
