These changes take the AWS SMS delivery from being suitable for ops alerts and the like, to being usable for end-user products.
On several projects where I've been involved, we'd have to justify why AWS could not be used, and why we needed a Twilio account instead, like the bad UX (non-customizable SNS opt-in messages) and US-only numbers. With these new capabilities, I think some non-trivial portion of AWS customers that are looking to add SMS messaging will pick this instead as the path of least resistance, even if Twilio is still more advanced.
You're right aws sms is good for quick implementation of basic sms setup into something already baked on aws. Also it will get better and better like any good aws offering. Good to have more alternatives to sms leader Twilio.
