Plunkr Case (Bug Reports)
https://stackblitz.com/edit/github-f2wj15-yqzqu3?file=src/app/app.component.html

Current behavior
When using p-radiobutton element with ReactiveFroms, once a radio button gets selected, it never gets unselected. However the form value updates properly.

Expected behavior
Only the current value should be selected on screen

Minimal reproduction of the problem with instructions
Just create a reactive form, with a form control, and a group of radiobuttons. This is a minimal reproduction of the problem:
https://stackblitz.com/edit/github-f2wj15-yqzqu3?file=src/app/app.component.html

and fix in #9265 (with b823983) only work for formControlName is same with name: https://stackblitz.com/edit/github-f2wj15-vde3mw?file=src%2Fapp%2Fapp.component.html

What is the motivation / use case for changing the behavior?
As the original issue is closed without proper fix, I re-report the issue
(related: #9440 , #9162)
The fix in #9265 (with b823983) is quite limited to the case using formControlName. If formControl is used instead of formControlName, the fix will just not work.

It seems the purpose of b823983 to add if (this.formControlName) condition in ngOnInit /ngOnDestroy/select is trying to not using registry for template-driven forms; but in that case should also take formControl under consideration.
Probably if (this.formControlName) condition in ngOnInit /ngOnDestroy/select should change to if (this.formControlName || this.fromControl) with @Input() formControl: AbstractControl;

@yigitfindikli could you please check this PR: #9632 for this issue? Thanks.

We are using PrimeNG in several frontend applications exclusively with reactive form.
Our ui is complex and with many nested formGroup, making hard to use formControlName.
Without this fix we cannot use PrimeNG >= 10 😢

IMHO this fix is urgent for core PrimeNG users to make p-radiobutton available for complex usage with reactive form
