Has Chrome been integrated to the TB yet on a detailed level? Those three extensions work so well that I'm not sure I could adapt to Safari without them...
Will the extension work in Canary? That reportedly already has touch bar support. I think Chrome is supposed to follow soon. Plenty of people use Chrome on the new MBPs anyway. The main drawback is when you're on battery. You can block most ads in Safari, but not the Youtube ones before the videos, as far as I've seen. Worth it to use Chrome for that probably. Runs fine on my 2016, but it makes my 2011 run warmer, so I try to stick to Safari on that one.
