Extend the email validator.

[n-hor]

We're working on a project that already uses Laravel default email validation in many places.
Now we need to extend it and the only simple solution we came up with is to override the validator with a custom one.

AppServiceProvider:

use Egulias\EmailValidator\EmailValidator;

public function boot()
{
      $this->app->bind(EmailValidator::class, CustomEmailValidator::class);
}

We are confused that this is a 3rd party dependency that Laravel uses and it can be broken after updates.
How safe is it and are there other ways to extend email validation without changing the 'email' rule in requests?

Just create a custom rule, and implement that?
