I have patches for necko part of this bug. We should work on the dom part of the implementation in bug 1409290.
Depends on: 1409290
Change to httpd.js test server and a test for the 103 response.
The change to nsHttpTransaction.
Propagate early hint response from parent to the child.
I have implemented a new interface nsIEarlyHintObserver instead of extended nsIRequestObserver.

It is possible to extend nsIRequestObserver as well, this only depends on how many observer we will really have and that depends on how we implement bug 1409290. Maybe we will need to propagate early hint responses through the listener chain(in that case we should extend the nsIRequestObserver interface).
Priority: P2 → P3

Any news on this?

I expect that website owners will only start to use early hints once a major browser supports it, but server-side support has been added in several servers/frameworks, for example:

Depends on: 1394778

nodejs also supports it
