We may see something similar come out of the Vivaldi project which is headed by folk who led the Opera <= v12 development who know very well what was lost when Opera moved to Chromium based web engine.
Case in point fresh Vivaldi on startup makes 4 connections to Google just to say hi, and will keep sending google delicious pieces of data throughout the day, not to mention hardcoded google DNS in case yours is too slow. How about spamming my local network with chromecast UDP garbage? or enumerating shares on startup? WTF would you even do that?
Ps I use Vivaldi :/.
Personally I still have Opera 12.18 installed on every computer as it still is the most swiss-army-knife browser out there for countless reasons. Most of the webpages can be made to work properly in it by adjusting the site preferences.
One thing I am yet to see any of the new browsers be capable of is complete popup blocking. Opera 12.x excelled at this and a complete blackout of popups is 100% achieveable.
