Adding an event to add code in case a customer was newly registered

[renttek]

Currently to check if a customer was registered by the observer, I am using an around plugin to check for this.
Something like this:

public function aroundExecute(ConvertGuestToCustomer $subject, callable $proceed, Observer $observer): void
{
    /** @var Quote $quote */
    $quote = $observer->getEvent()->getQuote();

    // Should be null for guest orders
    $customerIdBeforeObserver = (int)$quote->getCustomerId();

    $proceed($observer);

    // Will be set of the observer ran successfully
    $customerIdAfterObserver = (int)$quote->getCustomerId();

    if ($customerIdBeforeObserver === $customerIdAfterObserver || !$this->isCreateAccountChecked()) {
        return;
    }

    // my custom code here
}

Would it make sense to add an event in the observer?
Like this:

    public function execute(Observer $observer): void
    {
        // ...

        if ($this->newAccountConfig->sendPasswordMailEnabled()) {
            $this->sendPasswordResetEmail($customer->getEmail());
        }

        $this->eventManager->dispatch(
            'vendic_checkout_customer_created,
            [
                'quote'    => $quote,
                'order'    => $order,
                'customer' => $customer
            ]
        );
    }
