I get that decorators "can" perform the same task, but these are features that are standard in the language today. Once we start defining data properties on classes, there will be an immediate need to define the attributes of those properties. Yes, decorators can fill the need, but unless a standard library is provided to perform these tasks, there will certainly be multiple different takes on how such decorators should work. By defining them directly into the language like this, not only do we get a well defined approach to declaring properties with the desired attributes, but we avoid the additional complexity of decorator implementation for an otherwise trivial task.
...at least, that's how I'm thinking of it. I'm also working on 1 last proposal, proposal-class-modifiers with the intent of adding `abstract` and `final` to class declarations where `abstract class` would prevent instantiation of the class and `final` class would prevent inheritance of the class.
