I just heard of this a couple weeks ago and almost got bit by it. I was reading the console.log while debugging some code with the Opera browser and it contained a message warning me they were going to implement it in just a few weeks. For me it had to do with delivering .js app code from one server that connected to a CouchDB server running on a different vps, so the impact would've resulted in users calling and me having no clue about why things were broken. I don't know how I missed hearing about it before but the CouchDB team had already done what was needed on their end. Finding out how to implement it was a bit difficult for me though, but I got lucky when someone brought it up on the CouchDB users email list and their message pointed me to what I needed to do. I generally just glance at those emails. I suppose I ought to bookmark web.dev and make a point to visit it. Thank you for sharing that link dmix.
