Question about preflights for Private Network Access

[Adrián Romero]

Hello,

According the blog post published in the Chrome Developers blog https://developer.chrome.com/blog/private-network-access-preflight/ Chrome is deprecating access to private network endpoints from public sites sending CORS preflight requests for subresources.- And will extend these checks for web workers, navigations, iframes and popups. 

But the document does not says anything about requests starting from javascript. Using for example "fetch". 

Is there any plan to extend these checks to cover also js requests? If yes, for what Chrome version is it planned?

Thanks.

Adrián.
