Chrome has apparently just removed that feature.
I personally don't see any good reason why they should be hidden and would rather keep those displayed.
I know that Edge isn't technically Chrome/Chromium, but it is technically downstream of that project now, and a lot of what's being done upstream is... disturbing to me.
I don't know if there's talk about adopting or embracing this change yet, but if there is, I just wanted to put my two cents in and say I like the address bar the way it is now.
A while back we did test this feature out on Canary, and it was a mixed bag of feedback on it.
I feel like if we ever did adopt something this we would have an option to allow you to change it back in forth how you would like.
Thanks for the feedback,
Another vote for making it optional in that case. It helps troubbleshooting a lot to be able to see what protocol is being used
