New Release: Tor Browser 9.5:
Website publishers now can advertise their onion service to Tor users by adding an HTTP header. When visiting a website that has both an .onion address and Onion Location enabled via Tor Browser, users will be prompted about the onion service version of the site and will be asked to opt-in to upgrade to the onion service on their first use.

Has it been announced thay the feature will be included? I tested the protonmail website.but i didn't redirected to.the onion service.
edit: ok, so I have now learned that the ProtonMail Team will reply to or tag a post once a decision has been made to start work on the proposed feature or not. Would still be cool to have, but maybe the onion domain server doesn't have capacity for widespread use.
Thanks for adding this feature!!!

May it would look like this:
"meta http-equiv="onion-location" content="https://protonirockerxow.onion""
