I think we're positive on this. There are some technical issues to solve, but the concept is fine. The feature is something what web developers have asked for for decades, at least since https://bugzilla.mozilla.org/show_bug.cgi?id=254144 .

( So this doesn't mean the PR(s) can land, this means the concept is fine. )
