I’d use Alerts more if I could use them to activate a script that might create an audible notification on my Sonos speakers, send it to the TV’s and Text to the phone all at the same time.
If you combine the desired notifier platforms in a Notify Group you can target them all at the same time with an Alert.
Alternatively, you could trigger an automation based on the state of the alert entity.
Be aware that it is unlikely the Alert integration will be receiving any updates or new features going forward.
