What
Safari 11.1 shouldn't receive polyfill for fetch because it already has it
Details
We can see that https://caniuse.com/?search=fetch says that Safari supports fetch since 10.1
I've checked it on Browserstack (Mac OS Monterey, Safari 11.1), and it indeed loads a polyfill:
even though the browser has it anyway

The fetch polyfill also includes patches for Request, Response and Headers.
Some of these are required up to Safari 12.1

This might be related, but I noticed IntersectionObserver being polyfilled in Safari on iOS 15, when it already exists. So there might be some feature detection issues in Safari in general.
