Expose form status types (VALID, INVALID, PENDING, DISABLED)

🚀 feature request

Relevant Package

This feature request is for @angular/forms

Description

It would be great if form status types (such as `VALID`, `INVALID`, `PENDING `and `DISABLED`) would be exposed to public api

Describe the solution you'd like

Comparing form statuses to static strings eliminates Typescript as a concept, typechecking could benefit if these consts (which are already defined in forms/src/model.ts!) could be exposed.

In addition to that it would be possible to add a dedicated type for the status (see #28047):

import {VALID, INVALID, PENDING, DISABLED} from '@angular/forms';
export declare type FormControlStatus = VALID | INVALID | PENDING | DISABLED;
// or
export enum FormControlStatus {VALID = VALID, INVALID = INVALID, PENDING = PENDING, DISABLED = DISABLED}

That would make the available status self-documenting in TypeScript and also help with auto-completion in IDEs.

Any update on it ? Exposing this kind of enum would be create for avoiding magic string like
status === 'VALID'
