RC 6 Reactive Forms doesn't support disabled binding

I recently upgraded my project to RC 6. In my app we are using Reactive Forms. Among form fields there is a field which needs to be conditionally disabled.

Prior to RC 6 we were able to achieve this by applying disabled like like this.

<input formControlName="myField" type="text" [disabled]="form.controls.otherField.value">

After upgrade when I browse to that component, I see below warning in console.

It looks like you're using the disabled attribute with a reactive form directive. If you set disabled to true
      when you set up this control in your component class, the disabled attribute will actually be set in the DOM for you. We recommend using this approach to avoid 'changed after checked' errors.

      Example: 
      form = new FormGroup({
        first: new FormControl({value: 'Nancy', disabled: true}, Validators.required),
        last: new FormControl('Drew', Validators.required)
      });

I believe the the option to disable form field should be supported with Reactive Forms as well.

Currently to overcome this warning, we have to capture change event on otherField

(change)="onChange()"

onChange() {
        if (this.form.controls['otherField'].value) {
            this.form.controls['myField'].disabled = true;
        } else {
            this.form.controls['myField'].disabled = false;
        }
    }

@kara this issue is indeed a dupe, but https://github.com/angular/angular/issues/11271 is closed too. Shall it not be reopened, or are you not (re)considering to support the disabled attribute again?

ngOnChanges(changes){ if(this.isModify){ for(let prop in this.form.controls){ this.form.controls[prop].disable({onlySelf: true }) } }else{ for(let prop in this.form.controls){ this.form.controls[prop].enable({onlySelf: true }) } } } this is work for me
