My needing to rely on one modern browser engine is already too much software complexity for my tastes. In other words, I would have preferred to be able to live a typical day of my life without relying on any software as complicated (and consequently difficult for me to predict and control) as a modern browser engine. So, arranging for that typical day to be reliant on two browser engines is something I will strenuously try to avoid.
