Can change the credentials from 'include' to 'omit'?

[awong1900]

Hi, I have a cros error like this Reason: Credential is not supported if the CORS header ‘Access-Control-Allow-Origin’ is ‘*’.
usually, when use cdn like cloudfront, we set the ‘Access-Control-Allow-Origin’ is ‘*’. But if Credential is 'include' with Fetch API, the protocol do not support.

So i think the code here:

export function priority(url) {
  // TODO: Investigate using preload for high-priority
  // fetches. May have to sniff file-extension to provide
  // valid 'as' values. In the future, we may be able to
  // use Priority Hints here.
  //
  // As of 2018, fetch() is high-priority in Chrome
  // and medium-priority in Safari.
  return window.fetch ? fetch(url, {credentials: `include`}) : viaXHR(url);
}

to

export function priority(url) {
  // TODO: Investigate using preload for high-priority
  // fetches. May have to sniff file-extension to provide
  // valid 'as' values. In the future, we may be able to
  // use Priority Hints here.
  //
  // As of 2018, fetch() is high-priority in Chrome
  // and medium-priority in Safari.
  return window.fetch ? fetch(url, {credentials: `omit`}) : viaXHR(url);
}

What do you think with it?
