Via #6214 (comment)

importance was renamed to fetchpriority as part of the standards process.

I think every part is covered via MDN by now:

fetchpriority (#6213 (comment))
=> https://caniuse.com/?search=fetchpriority

"the priority attribute on the RequestInfo of fetch"
=> https://caniuse.com/mdn-api_request_priority

The data specifically refers that:
https://github.com/mdn/browser-compat-data/blob/49d96ed28c8ab1184be01328c3d7c596b1ef365a/api/Request.json#L1107-L1109

Not saying this isn't useful as a combined feature on caniuse, just for the record.
