Are CDNs that don't cache useful?

Is there any benefit to (HTTP-) serving a non-cacheable resource over a CDN?

(my use case: I'm serving a static Single Page App and I'd like to improve its load time, but I don't want index.html to get cached, because I want every new release to be reflected immediately. Specifically, this static site is hosted on AWS S3, and the CDN is AWS CloudFront.)

I assume that most of the performance benefits of CDNs are achieved through caching, but I could imagine other benefits due to, say, priviledged network infrastructure. As I don't know the first thing about networks, this may sound like a silly question.

Yes, it can be useful by moving the content closer to the user. Most CDN's will serve your static file from a geographical location as close to the user as possible, typically providing better latency.

Of course, you need to have users across the globe for this to make sense to you.
